personally i like the majority of perp dex teams on solana, whether their engines are onchain or off chain
phoenix guys are great. they built one of the best propamms in the space and are brilliant quants
pacifica are ingenious pulling strong volumes, implemented tap to trade and are working on cool options stuff
bulk lads are eyeing more arcane markets and i am told are cooking
bullet, gmt etc are all solid guys as well
either way solana will be upgraded within 12 months and they can bring the majority of their architecture onchain.
until then, lets just ship as many cool products as possible
