I'm a big fan of small pots. The most important reason is because the substrate dries out faster and so fungis won't like this substrate and you are on a bit more safety side concerning root rot. I've never lost a plant because it didn't got enough water but several because of root rot. Sure it is also depending on how big the roots of your plants will get but even for raffs and globosas this works for me. For highland plants, epiphytes and lytophytes you can really go for small pots.
Also you don't need so much substrate and space.
I'll post tomorrow some photos of some of my plants which have really small pots considering their size.
Edit:
I read that you've got also hydroponics if you grow your plants in nutrient free substrate like burned clay, sphagnum or whatever we use and give the plants the needed nutrients via watering. Plants grown in hydroponic systems are mostly faster growing because they get their nutrients controlled in shorter intervals. So the smaller the pots the shorter are the intervals of watering. So in theory the plants should even better growing.
