I have Rev'It Poseidon which is a laminated gortex suit. You can read my experience of it in the link below. It hasn't leaked since that episode (It's 4 years old now although wasn't really used in the first 6 months of it's life), but setting that aside here's a quick summary:
Pros: Laminated Gortex is brilliant especially if you ride all year round. Your clothes don't soak up the water and dry very quickly. It doesn't matter what the weather is going to be like and you don't have to faff about adding layers if there's a downpour. I'd always recommend you buy Gortex, and would recommend laminated gortex.
Cons:
It was very expensive when I bought it (and I only did so due to the amount of times I ride in the rain)
There's a few panels that started peeling off very early in the life of the jacket.
I previously had external chest pockets on the jacket which this doesn't have. 4 years later I still miss them.
The internal chest pockets aren't that easy to access to get your phone out.
The venting system isn't that great (certainly not on the V-Strom). Whether it'd be better on a naked bike
The chest vents also look like you're trying to show your tits off
and as they use magnets you can't use the jacket if you have a pacemaker.
I find the cuffs don't work as well with gloves as my old Hein Gericke jacket did. Make sure whatever you buy works well with the rest of your kit.
