oooooo..... tough to say. They are very different platforms. I personally like my BG4 better because its a rare kit, and just turns more heads. Of course this has nothing to do with actual performance.
The BG4 is actually more like a 1/14th scale in size, so its much more stable than any 1/18th. The wheel base is extendend over an inch vs the regular m18T kit. It feels more planted on rough tracks, over jumps, etc... but the turning radius has increased accordingly.
I prefer the handling on the xray mini's, but both the M18T and Vendetta are very solid in that department. The M18T bellcrank unit is simple, tight, and responsive. There is no slop from the get go. The detta needs a servo brace to cut out the slop (they mounted the servo with just 2-sided tape... can you believe that???).
A little background info on the Detta:
Anderson Racing in Taiwan is the OEM company which sells the MQ/MRX-4 and Vendetta/MB4 around the world under different brands. So if you have an FTX blaze (U.K.), LRP Shark (Europe), Yokomo MB4 (Japan), its all the same as the Detta in the USA.
Downsides of the detta:
- 48 metric (.6 mod) pitch on the pinion/spur gears. Unique to mini's.
- 2.3mm bore pinions on stock motor. (Not a big problem, you can always buy a 3.2mm 400 size motor and use RRP 48p metric pinions).
- Most LHS do not stock duratrax spares... at least not by me.
- Less aftermarket support vs Losi or AE.
- Stock outdrives and universals are weak. The steel cvd set includes outdrives, so that's good.
- Stock electronics are god awful. They should go straight to ebay for the next unlucky schmuck... lol... that's mean I know, but someone's trash may be another's treasure...
Now, don't let this deter you from giving the Vendetta ST a shot. Its a great mini, and is equally capable as a race platform or a basher.
