In reply to Rory Shaw:
One of the issues here is that what many people consider to be 'softshell' is 'windproof stretchy outer with bonded fleece (sometimes even membraned) backer'. This is just one very tiny subgenre of softshell, one that has become harder and harder to find on the market as hardshells have become more stretchy and breathable in the last couple of years - as Rab Kinetic and for example The North Face FutureLight and Fjällräven Eco-Shells demonstrate.
Stretchy windbreaker is just another subgenre of softshell, in most cases indeed far superior to the old school windstopper fleece softshell.
With regards to OP's question, I have no experience with any of the jackets you mentioned but I love the Rab Torque jacket for anything in wind and a shower here and there. Feels good, fit is nice and athletic with just enough layering space for one thin puffy, helmet hood is great and pockets are big enough for serious gloves. Also, the reinforcements are well placed for the ruff stuff. It is very similar in feel to the Gamma LT actually, although that one seems to be a bit cleaner in design.
