No, the inserts are exactly the same for all 9mm double stack Glock mags. The inserts are different between the two base plates.
What insert you would run is great, and may even work depending on how you use them. My comment is based on first hand experience of actually using them, not what would happen if I did. I have had my own fly off, on a mag I bought used. One didn't have the insert and was off a few times before I called Glock and spoke to them. They sent me an insert and no more problems. The second incident was at an IPSC match a guy had the exact same problem. He bought +2 bases with no inserts, not knowing any different. I loaned him a few inserts for the day and he was good all day.
Admittedly the only time I saw it was partly filled magazines, on tactical reloads. The added weight and spring pressure can push the base right off with a proper bump. If you don't believe me, grab a mag and push the base with your thumb. It should come right off, as there is nothing blocking it.
What? I'm not even sure what you are suggesting here, unless you means easier to disassemble than a welded mag such as 1911 or the like. Mags are way easier to dissassemble with no insert. The base plate insert's primary purpose is to lock the base plate to the mag body. That is why it has the bump to mate the hole in the plate, and the +2 has the splines that match the slots on the +2 insert.
Neither are these. I run mostly the 10/19 mags shown here and well over 20,000 rounds on those 10 mags. All are factory Glock mags, other than 2 Pmags which came with purchased guns.
The insert protrudes above the base plate, and the tip engages the mag body.
The tip of the insert against the inside of the mag body.
Of course the locking tab doesn't line up with the +2 base.
