Conical would tend to give more mouth feel.
Which of the grinders you tried were the preferred ones for you? Then can narrow it down
Must admit just having got the niche it’s not as massive a difference I thought it would be to the 83mm flat of the mazzer

I think the differences are quite subtle. The other thing people don’t realise is that the usual big commercial grinders designed to run with a full hopper of beans, in general were not built with close tolerances in mind. Unlike the more boutique grinders, Lagom, Kafatek, even Niche etc… They were built as rough tuff commercial workhorses,
I guess you might see a bigger difference with a grinder that has closer tolerances? It’s still small improvements, for lots of extra money. For some people they simply need the surety that they have the “best” possible grinder at the moment, often coupled with the “best” possible equipment. Usually this best is decided on price and cachet….can they taste the difference…who knows, is it worth it, yes it is to them.
For me I simply want a cup of coffee with minimal faff….my interests also lie in improving “relatively affordable” equipment, as I can then have a positive effect on the enjoyment of coffee on the maximum number of people. Rather than putting loads of work/time into a relatively Niche product and you can’t buy time.
The type of coffee you’ve described is my exact preference for espresso/flat-white. I’m not a world-class barista by any stretch of the imagination but I’ve made a lot of med-dark espresso.
I also don’t have a huge amount of experience with comparing grinders as all but one of my espresso grinders have been flat burr. But to me, Mazzer (58mm and 64mm) just does such a great job of that style of coffee that I’ve come back to a Mazzer twice after trying other grinders.
The Super Jolly I just got, despite being a pretty dated grinder these days, consistently produces thick, rich, chocolatey espresso over and over.
For brew, I’d always choose a conical but for espresso, a big ol’ no-frills flat-burr will always be my choice.
I’m also still not completely convinced that single-dosing for this type of roast has the noticeable benefits it does for lighter roasts vs on-demand.
Before the pitchforks get thrown, I’m not saying there’s no difference, there obviously is, but dark roasts seem more forgiving to me. When single-dosing isn’t a factor in choosing a grinder it opens up a world of possibilities. VA Mythos, Compak, Mahlkönig etc.
Compared to Niche and DF64 with ssp hu, I’ve got huge leap forward in thick body, chocolaty taste and overall complexity from a Mazzer Major with stock TiN coated burrs. 
Cuprajake I liked the Niche and I really like the EG-1 and the Kinu M47 Classic. The Kinu gives a bit more clarity and the Niche a bit more chocolate (some would say muddy) flavor. Both give pretty darned tasty espresso. The EG-1 is for the best all rounder that I’ve had.
After 8 grinders I’m really resonating with what @DavecUK is saying about the differences being subtle and the chasing of probable diminishing returns of the Holy-Grail, God-Shot, Influencer-Endorsed, Boutique-Waiting-List-Cos-We’re-Amazing, End-Game grinder.
Kind of hoping that my grinder wanderlust will quiten down once I’ve dropped the Mazzer 83mm conical burrs into the Malwani Livi and have them seasoned and I’m cranking out some dark roasted AAA Kenyans in the Streitman and I’m blown away with the flavor.
Or maybe I just need someone to slap me hard and say “enough already, what you’ve got is as good as it gets” 🤔 🙂
In the meantime I would really love to hear your specific likes.
Can I ask whether you think the SSP burrs on the Solo are a worthwhile upgrade on the stock burrs?
Cuprajake I’d also put forward a placebo effect on that when people spend so much money it will taste better
Mind you, MC Donald’s seem to have been the exception. Very cheap and taste fantastic for some reason.

Right. Now confirmed your tastebuds are not as good as they used to be. 😬🤦♂️😊🤣😉😂🙃🍭🍿
Thanks mate. Quite intrigued to see what difference that they may make, but wonder whether the outlay is worth it. Not to mrntion thr ball-ache of trying to align them
Just saw on instagram that Titus is about to release a new grinder. First it has a prebreaker and then a 74mm flat burr where you can choose between SSP, Gorilla and Eureka. Should be good for both medium and dark I think.
It’s ok, no one will be able to afford it anyway.

I find smashing dark roasted beans with a meat tenderizer gives a nice mouth feel. 
Sham I think that Monolith does a dual set of burrs on some grinders.
“Dual-conical burrs, first in the world. 71mm “pancake” burrs designed and made in house for coarse pre-grind stage and 71mm Conical Burrs for fine second grinding stage (Mazzer 186c)”
audiomacgyver I think the first burr set has about the same purpose as the prebreaker. Also Versalab and Honne have two burr sets but there the last burr set is flat and the first is conical.
