Doing B you would save a lot of money
😉, but If you can afford it and you really like it, do A, because you can still keep enjoying your mechanical modules “Connected to Eternity” with the modular accessories. And if you are not iPhone user, then you can tether more than one smartwatch to your phone, so you would still enjoy your Connected Modular 45 (I’m iPhone user, and this is one of the main reasons I did B)
About which one of these three Gen3, I would take the one with steel bracelet, and I would then order a rubber strap (for instance the black rubber strap with red stitching). If you buy it in this order, it’s much cheaper than buying now the watch with rubber strap and later the steel bracelet
Anyway my favourite Gen3 is the black titanium case, but steel with black ceramic bezel would be my second choice
