Absolutely nothing wrong with the Mossbergs that I own. Some of which are being used by generation #4 in my family. I have a model 500 that is now my wife's, two of their old bolt shotguns that I use, A model 200k that I still use (was great grandpa's), and a 151 m .22 LR that was my grandfathers, which is now used by my step-daughter as a plinker. I used to have a Maverick 88 and a model 5500 at one time, they were traded off shortly after I bought my Remington 870. Once I shot the Remington a few times, I found it easier to operate, ( I'm 5'8, and left handed. The 870's trigger group is closer to the grip than the 500's, and the slide release is further forward and not rubbing against the inside of my trigger finger. I hate having short fingers!) and slightly better fitting. That is why I mainly use the 870 instead of a 500. My step-daughter also has an 870 due to prefering how it feels to her.
I think most of the 500, 590, and 835 bashing going on is people who have never fired one putting to much faith in what they hear from others who also have never even handled one. It's not the gun, it's the operator in most cases. If you are happy with your 500, then good for you, and enjoy it.
I was happy with my old 88 since my parents bought it for me (I saved all summer until deer season and gave them the money) when I was 17, and used it for 18 years before trying out a friend's 870. Dad used the 5500 for 20 plus years before he gave it to me (except when he would still hunt during deer season, he would always swap out for my 88 because it was lighter) I just never used it because of how heavy it was, My wife used it for two years before I got her 500. Once she got that, she stopped using the 5500, and it got traded off. Point is, It's all about what you are comfotable with, and how you are going to use it, not what other's judge it to be.
If it ain't got papers, deport it.
