Excellent review Chunder, couldn't agree more, been working this out over the last few years as well.
I've got Gators 5.3, 5.7, 6.0 and blades 4.2, 4.7, 5.3, 5.7. Boards 106L FSW (quite a wavy one), 102L quad, 86L quad. I'm 90kg
we can have quite big waves and light wind some days in western Vic (dead cross shore) and there is little in the way of a channel, hence need the power to get out with. That's where my 6.0 and 106 come in good. I've tried a 6.2 blade, however found the 6.0 gator just as manoeuvrable but with way better bottom end. It's only when you are coming off the lip (late) when powered up, in big waves, that it may tend to push you around a little more than the blade, however all the other advantages out way this
Concur with your comments that the gator is slightly softer than the blade. I've gone to using the Gators as much as possible because of this, there is less spike coming through the rig when faced with choppy conditions meaning that you have a more controlled and comfortable ride. Somewhere around 2020-21 the blades moved to a slightly higher skin tension and draft further back (had to move my harness lines back 2cm), which as you described makes them more immediate (reactive) but twitchy, compared to the older blades.
I've got a 5.3 gator, I've only used it twice, in cross on conditions. I've yet to use it in big waves and cross shore conditions. It's quite different to the 5.7 and 6.0, in that it has a Dacron luff panel like a blade. It seems wavier than the 5.7&6.0. I can't wait to test it out and compare it to the 5.3 blade in hard core wave conditions.
I think the Gators are a really underestimated range in the Severne line up. With its progressive geometry as you move the sizes, it really suits 90% of the conditions you find yourself in, you just got to pair it with the right board for the conditions then.
I'm interested in anyone's views on the smaller sizes <5.3, how they compare to the blades in cross shore wave conditions
