The mec gar base plates on the 14rd mages are their Achilles heel when it comes to hard usage - although you can't get anything lower profile for concealed carry as far as I know so I still think they serve a purpose there.
I would second DenStinett's suggestion on using the rubber base plates. They are going to be the most cost effective and, in my experience, stand up well to competition usage, especially at indoor matches where mags smash into the concrete pretty forcibly.
For removing the stuck plates I had some success putting mine in vice (light amount of compression on the vice) and flatting out the edges using a wooden mallet which helped loosen out the the spring steel base pads warping around the tabs of the magazine body - which causes this stuck issue.
Also, for concealed carry, I really like the CGW aluminum base pads. They are quite aethestically pleasing and well made, imho, but are too pricey for me to run on all my comp mags so I have no data on how they would hold up to abuse - I imagine just some scratching and marring.
