Funny enough I always found the opposite, I find Renoise great for making short loops but putting them together into a full track to be a pain, and then visa-versa with Ableton and software like it.

The OP-1 is where I've found this to be especially the case, incredibly easy to make a loop on but never managed to make a full song on it, aside from using mutes/effects on a single loop to stretch it out into a full track
