I've been heavily leaning towards the Bravo 5 myself. One of the benefits is that it's a prisim site, the reticle is etched in to the glass so even in the event of a battery failure you still have your sights.
I wouldn't use cartridge cleaner in it, use the Hornady Gun Parts Cleaner. It says it is safe for all gun finishes. You can even call their customer support to verify. Here is what I am referring to. Cleaner
Only thing I keep in Bins is my hunting gear. Got a few, one for each area I hunt. All stored with local foliage from those areas. What kind of gear you talking?
Have you seen the Gerber MP600? Santa just bought me one about an hour ago. http://www.amazon.com/gp/product/B00783N8M4/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
P223 on a 16" here. Fixed magnification. Great scope. Very pleased with it. One thing to note is that the M223 scope mount does not work with it.... I found out the hard way.
I can only speak for the EoTech. I have the 512. Absolutely love it. Have had zero issues with it and holds its zero perfectly. You're welcome to try her out if you'd like.
