Any of those would suffice as a great first - and lifetime - shotgun. While I have Winchester and Remington 20" and shorter shotguns, I've preferred Mossberg as well for a long time. I run 14" 590s primarily, give up capacity but gain a bit in the ability to move through structures especially in low light - I realize 14" shoulder supported weapons are a bit of a PITA in the USA, and it's really not a major difference going to a longer one for me. Having the Mossy speed stock and a side saddle = 15 rounds on the gun, which isn't terrible for a 14 inch shotgun. The safety position on the 88 is a button on the trigger guard compared to the tang mounted slider on the 590s, that's the only pref I have and in the grand scheme doesn't make a lot of difference overall.
I wasn't impressed with the 590 at first due to the extra time it takes to break down and reassemble over the other options, but I got used to it, and they've been great, I've run my first 14" now for over 16 years. I've had an 88 6 shooter since 2005, you can't beat them for the money.
