Does your rifle have the optics/accuracy that using a match trigger would allow you to take full advantage of? If not, then definitely no.
If you must have a match trigger on your "SHTF" rifle, keep a regular fire control parts set in your gear or preferably on the rifle so you can change them out if neccessary (preferably not while taking fire, or being mauled by animals).
The modular trigger packs are the only ones I would consider for serious use, simply because there is less to go wrong with them. Several of my friends have thousands of rounds through these without problems...I'll be convinced after I get one and it works the same for me.
