I have a couple of Scorpions, and they are similar in brightness to the same catagory SF lights (G2, 6P).

Some people like the rubber grip and some do not. The upside of the grip is that it you get a very secure and conformatble grip. The downside is that it is harder to pull out of a (tighish) pocket or sheath. Personally I like it. The G2 on the other hand isn't rubbery, but does have some texture to it and isn't slippery. The non black colors (yellow in particular) do collect dirt stains.

The clickie style tailcap works very easily and is nice to use. It isn't built as well as the SF tailcaps, so hard use might damage it.

It is possible to accidently active the light in your pocket. And if you do, you can melt the lens (and you'll say "ouch, that's hot!"). I assume it is possible to melt the lens on the G2 as well and the old style w/o the lockout tailcap would not have anything to prevent this. Of course, since it is momentary activation on the G2, it is less likely to be on long enough to melt the lens. Of course since the button sticks out, you are more likely to activate it here and there.

The rubber sheath can get damaged / cut up in some cases. Most typically this would be a "compression" type cut at the tail end. Basically drop it on it's tail and the metal in the light can cut the rubber. Dogs also like to chew up the Scorpion. :-O SL has a warantee, but my attempts to get them just to sell me a replacement rubber sleeve were unsuccessful.

The rubber is part of the water resistance, so if it is cut, the water resitance is compromised. However, the Scorpion design is inherently only splash restaint IMO and cannot easily be made waterrproof. OTOH, the (old style) G2 tailcap isn't waterproof at all.

The real problem with the Scorpion however is the lamp assembly. It uses a bi-pin lamp, and it is possible to dislodge it by dropping it, or in storage if it moves around. The problem is bad because 1) the light doesn't work when you need it, and 2) because the light falls into the head assembly which is sealed and has a "rubber" seal at the opening. It becomes a long exercise with needle nose pliers or tweezers to shake the bulb around until you can snag a leg of the bulb and coax it out. The little rubber thingy at the entrance which provides shock issolation and retention really works against you in this case. The G2 on the other hand has an integrated lamp assembly and this isn't a problem.

All in all, the (old style) G2 and the Scorpion are very comprable. I'd give a slight nod to the G2 only because of the lamp retention issue which is a serious design flaw IMO and can leave you w/o light, w/o notice at any time. The old G2 has a serious design flaw in that it's tailcap is in no way waterproof and the button falls out when you are changing the battery, but those are more managable issues.

The new style G2 lockout tailcap is supposed to be waterproof and not have any parts that fall out. In that regard, I think it is clear the new style G2 is much better than the Scorpion and for about the same price.
