They both will eat veggies and worms and pellets and waffers. Lots of protein if you want them to grow fast.(fast for a pleco) Plecos love to hiode it is what they do most of the time.
I always fed all my plecos NLS only with a zucchinni once in awhile and they were always fine and grew well for plecos. I think commons and sailfins are the only plecos that grow really fast. Any of my pseudacanthicas plecos including my female L-25 will never touch any veggies.
you may have comparability issues with the L007 and L048. The L48 usually gets picked on by the more carnivorous plecos. Option 2 seems the best to me.
