I kind of agree. I respect Kingler, but I've used him myself and I really didn't like him, so I don't really experiment with him any more. There is a gap between things I respect and things I would use personally.
Sandslash is the one I love to throw in there every now and then. 100 Base attack +STAB EQ is pretty nice, and after a Swords Dance it can really surprise people.
The issue being, of course, that STAB EQ isn't as useful for a Swords Dancer as it is for a hit-and-run attacker like Golem or Rhydon, due to Hyper Beam's increased effectiveness when boosted. I mean, here's the full list of things that +2 Sandslash can KO faster than +2 Kingler:
Gengar (Sandslash OHKOs vs. Kingler usually 3HKOs)
Cloyster (Sandslash usually 2HKOs vs. Kingler sometimes 2HKOs)
Slowbro (Sandslash always 2HKOs vs. Kingler usually 2HKOs)
Omastar (Sandslash OHKOs vs. Kingler 3HKOs)
Kabutops (Sandslash OHKOs vs. Kingler usually 2HKOs)
Weezing (Sandslash OHKOs vs. Kingler 2HKOs)
Nidoqueen (Sandslash OHKOs vs. Kingler 2HKOs)
Muk (Sandslash OHKOs vs. Kingler 2HKOs)
Arcanine (Sandslash OHKOs vs. Kingler 2HKOs)
Nidoking (Sandslash OHKOs vs. Kingler 2HKOs)
Magneton (Sandslash OHKOs vs. Kingler safely 2HKOs or sometimes OHKOs)
Ninetales (Sandslash OHKOs vs. Kingler safely 2HKOs or sometimes OHKOs)
Tentacruel (Sandslash OHKOs vs. Kingler safely 2HKOs or usually OHKOs)
Koffing (Sandslash OHKOs vs. Kingler safely 2HKOs or usually OHKOs)
Omanyte (Sandslash OHKOs vs. Kingler usually 2HKOs)
Nidorina (Sandslash OHKOs vs. Kingler safely 2HKOs or usually OHKOs)
Rapidash (Sandslash OHKOs vs. Kingler safely 2HKOs or usually OHKOs)
Kabuto (Sandslash OHKOs vs. Kingler 2HKOs)
Scyther (Sandslash OHKOs with Rock Slide vs. Kingler safely 2HKOs or sometimes OHKOs)
Charizard (Sandslash OHKOs with Rock Slide vs. Kingler 2HKOs)
Moltres (Sandslash OHKOs with Rock Slide vs. Kingler 2HKOs)
Articuno (Sandslash OHKOs with Rock Slide vs. Kingler 2HKOs)
Hmm. That's actually more than I thought there'd be. Still. The only ones there you're going to see in OU are Gengar, Cloyster, Slowbro, and Articuno, and as Sandslash is outsped and OHKOed by Cloyster and Articuno, it's not going to be accomplishing anything against them anyway.
Point is, Sandslash ends up KOing mostly the same or less stuff compared to Kingler (except Gengar) and also doesn't threaten things unboosted the way Kingler does with Crabhammer.
Victreebel's still the best Swords Dancer, though, since not only is it one of the best on sweeper merit (+2 HB can sometimes OHKO Chansey, Razor Leaf not only OHKOs Golem and Rhydon but also threatens Starmie with a near-OHKO), but its movepool is wide enough that it's not 100% predictably a Swords Dancer.
The other Swords Dancer I'd respect would be Kabutops. It doesn't quite have Kingler's power, but unlike Kingler it does legitimately have some things it can use as setup bait (Hyper Beams, stuff with Ice/Normal coverage) and it also has Slash (fun fact: Kabutops's Slash does identical damage to Sandslash's Earthquake against neutral targets).
