I know there are a few companies testing big bore shocks (TQ and Kyosho). I am interested in getting these. I run AE shocks on my truck and 4wd but run Losi on my buggy. I can't tell the differance. I use them both because I have plenty of spares from older kits. A properly built AE shock will function just as well as a properly built Losi shock. Kyosho does make the best shock though.
