SEVA-D vs PSZ-20W Convoy + MASK-1 Helmet

[Magnus]

Found the SEVA-D suit pretty early, and now I've picked up both the PSZ-20W Convoy and Mask 1 Helmet.
Should I keep using my already upgraded SEVA-D Suit, or would I be better off switching to my new armor and helmet?

Also found the Integral A SMG, but already got Shah's mate. I rarely use SMG, but which would be the better pick?

SEVA-D is 2nd or 3rd best when fully upgraded, 5 artifact slots, 1-2 lead containers, good all around protection. Solid choice for early-mid game. Only one I have found that is better so far is the PSZ-91 Falcon. The Convoy vest was ok, but there are better vests/helm combos. I also found the lack of artifact slots in the convoy to be a non-starter especially since I already had a partially upgraded SEVA-D when I first got it. Also note, it is generally more expensive to repair a vest/helm combo than a single full suit. Food for thought, as repairs can drain your wallet quickly until you get established.

Ok thanks for clarifying. Not always easy to know what to go for since I'm comparing an upgraded version to non-upgraded ones that I just obtained.

Also got the "regular" SEVA suit - is the SEVA-D better?
