I Like the TQ a lot, though buy the kit if you get the choice as most hobao electrics in the RTRs isn't so good, and its always recommended to strip down and rebeuild RTRs anyway as the build quality in (all RTRs not just hobao's) is dubious.
The Buggies however are very tough and have a wide range of hop-ups available.
The PBS is slightly tougher whilst the TQ steers better in my opinion. If your buying the RTRs (which I assume you will) the PBS comes with the hyper 8 port engine and the TQ comes with the hyper 4 port or the mach .28.
If you want the best of both worlds get the TQ kit, then go buy CNC hyper 8 knuckles, CNC chassis braces and a hyper 8 port all cheap off ebay. You will then have a Super tough cheap and fast buggy for not a lot of moolah.
