Worth MTMing R4 rewards?

Ive come to the point now where im costantly running out of upgrade resources as Ive been MTMing everything that I get even though they dont make my deck. So was wondering is there any real point to MTMing the R4s? Should I just trans scan these cards so there in my cyberdex and have done with it? As far as I can see theres no difference to the cyberdex if their fully MTMd or just trans scanned so whats peoples thoughts on this? Oh and while Im at it ive also got a raft of old episode weapon cards that will never be used so should I start using them up to uprgrade my R5 weapons?
