I've been running a Raven Phantom for about a year, and also recently bought a Bravo Concealment RTT combo pack(with the two SINGLE magazine carrier option).
While I will say that it is hard to beat Raven, I bough my Bravo gear with the purpose of carrying OWB. I run the Raven Phantom IWB with the offset wings and soft loops. And as for IWB, it is the absolute best carry system I have ever run.
That being said, Bravo has won my future purchases for Kydex. At least for now. Here's why:
1. I received my Bravo order exactly 6 weeks from the day that I ordered it. The lead time was quoted 4-6 weeks. To have it to my door, the day of week 6 was nice.
2. My Bravo holster is much more finely crafted than my Raven. I know that Raven is known for a high quality product. But when I first got my Raven a year ago, it had next to ZERO retention. I had to use a heat gun to press the trigger guard area of the holster in to get that nice click and solid retention that Kydex is typically known for. I had no such problem with my Bravo. Perfect retention, and the draw is very smooth, right out of the box.
3. I really do think Bravo is trying to innovate and step up their game. They do a lot of advertising with TheBlaze and elsewhere. I can only imagine that has generated a TON of revenue for them. In turn, giving them more money with which to invest in new product(e.g. the Acer).
4. The magazine pouches(at least the ones I got) win me over the Raven ones, simply because they have a very positive retention, and they don't use the stupid tension screw like the Raven ones. I've found that even with the tension screw that the Raven ones have, I can't get the solid retention that I would prefer. The Bravos win me over in that regard.
