From my limited experience in competition, shooting side by side against the best of everything out there, a loaded up Bravo is as good as anything else and better than most.
...assuming one planned on a Howa 1500 SA + heavier 26" MTU/M24-ish contour:
Bravo for Howa 1500 SA
Chassis 440
T-slot weight 70
Heavy ARCA rail 100
Heavy ARCA spacer 100
Heavy LOP spacers 26 per
Spigot 70-123
...depending on whether the minimalist spigot (70) will work or the ARCA spigot is needed (123), and whether you want to run 1-3 LOP weights (26-78), the rig will end up ~21-23lbs and be more capable, just about as nice, and feel similar to something really nice like a Manners PRS-TCS with the heavier steel rail and all 5 weights (the other chassis I'm most familiar with).
Total "match ready" cost = ~$806-911 (add another 60 if you need/want a pair GrayOps m-lok weights up front)
MDT ACC for Howa 1500 SA
Chassis 1190
Internal weights 145
External m-lok weights (2 pair) 120
Buttstock weight 60
Bagrider 50
...~23lbs, feels like a 100% aluminum chassis (not better or worse, just different, less dead-feeling maybe IMHO), options for adding even more weight (.75lbs per mlok weight pair).
Total "match ready" cost = ~$1600
There is a bit of a stigma attached to the Bravo's as people view them as "that $350 ubiquitous entry-level chassis", and they make a pretty crappy/underwhelming first impression. More "barreled-action holder" than "match ready" IMO. But, if you take one and go a la carte and trick it out, it becomes something else entirely, and honestly will change a few peoples minds about them when they handle/shoot one that has been fully blown out from the KRG side menu.
An out-of-the-box ACC gives a great first impression, and feels like a much higher quality piece, because it is and should, it costs ~3x as much. But, it's not really "match ready" either without spending more than a few more bucks, and arguably, in some ways they're not really even "bench ready" until you attach a bag rider of some type. Though, it's the tops in MDT's range and is an awesome chassis for "joe's" as well as the "pro's".
Spend half and go with the Bravo and you'll have a sick rifle but there will always be a few rifle snobs looking down their noses at you. You probably won't get that vibe from the rifle-snob crowd with an ACC, but they have been selling factory Savages wearing them, so that may not last forever... IMHO they're equally capable.
Pick your poison.
