Space missions, at least in the mid-levels, are paying out ridiculous amounts of xp right now, get your free XP before it gets nerfed.
Don't just run the missions though, use the damn terminal right behind you on your ship and run the ops.
I did lvl 24 on my scoundrel in about 30 minutes, and then tried it on my 16 Jug and did a whole lvl in 20 min.
Lots of comms too, but only for spacy stuff. I would probably get bored doing nothing but space (not to mention horribly outpace my gear/make next to no money per lvl) but if you have an area on the ground that's kicking your butt because you need an extra lvl, run a few space ops and go back after you ding
