I have tried both - and let me say - to both modders - great work!
Trigger Maru is designed to make the game more playable - RFB is made to make the game more historically accurate. Each has their upsides. I have enjoyed both, and thank the modders for the effort.
I do usually play using RFB - but have included Kakemans improved escorts as well - it is for me the best of both worlds. The escorts in stock RFB still seemed to be asleep at their posts.
The question is really what type of game do you want. Both deliver unique and enjoyable gameplay - which one you will want will depend on your style.
