Belts vs Bots, Science Labs Edition!

Hello all!

I'm aware the discussion of the Belts versus Bots versus Trains is a discussion as old as each of those items in the game, but I constantly see only belts in peoples' screenshots for labs.

Personally I have labs with prod modules surrounded by speed beacons and fed by requester chests, each chest requesting a Nauvis science and an other-planet science. Currently sitting pretty at 2.6K SPM, chugging along towards Steel productivity 40 (yes, it's days per science at this point).

However, I haven't hit Gleba nor Aquilo yet, will this be a problem with bioscience? Are there other pitfalls I'm not seeing?
