So many varieties of splat, so many great recommendations. Devi is the Queen of gate and splat, and has a rainbow of flavors, previously noted. The Fuzzhugger Velcroar is awesome for splat, but as intended by Tom D., not as much with the gate (although I'm sure the Velcroscillator version can get much more gated). (Also--did anyone say Fix'd Fuzz yet?)
I think of splatty as describing both attack and decay, but moreso the attack. Gated, I think everyone understands as truncated sustain/decay. How truncated do you want the sustain/decay, and do you want it to just cut the note of clean, or sputter a bit for it dies completely?
Rather than just continue to throw out names of moar and moar different fuzzes, I'll suggest you look for fuzzes that allow you to adjust bias, sag/voltage, or even better, both. I've gotten gated splatt tones from the MI Audio Neo and EHX Germ 4 BMP, although I don't view either of those as fundamentally gated or splatty. I just recently got a 69 (SI Fuzz Face) from St

that can really bring the splat and gate both [Edit--this was in a cold room--when I noticed and warmed things up to room temperature this fuzz became very reluctant to gate, and any splat was decidedly dainty--so here's an idea--put your fuzz in a meat locker].
If the fuzz also has a feedback/oscillation circuit (see Velcroscillator), this can lead to more fundamental gatedness in certain settings, or can power through the gate to make useful an otherwise unusable gated setting (eg. one that cuts the notes so short you lose intelligibility because it's all attack, no fundamental and it starts to sound like you're getting tracking misfires; or one where the attack and/or decay are too unpredictable to create consistent musical results).
ILF Member Sunmachine (Chris at Sunmachine Sonic Devices in Germany) has made me an incredible version of Dragonfly's DIY Classic Seven Fuzz plus a Green Ringer AND a Tim Escobedo Psychtar, called the Seven FInger Death Punch, which was demoed by Kayzer (see
here:
http://ilovefuzz.com/viewtopic.php?f=14 ... ne#p295423) that does the widest variety of Splat and Gate of any pedal I've ever played--I've been meaning to give it a proper write-up because I think it is something the ILF 'hood at large would really enjoy, but I'm trying to work the kinks out of my demo machinery first.
And if Devi is the Queen of Gated/Splatty Fuzzes, Joh Lyons @ Basic Audio is surely the King--I'm housing a mini-tourbox of seven Basic Audio fuzzes right now that I need to do a write-up on, and almost all of them will go gated and/or spluttery--rather than just list all of his fuzz, I'll suggest you contact John, who is a super nice, approachable, knowledgable and intuitive guy, and describe for him what you're looking for--he'll be able to hook you up for sure at a very reasonable price.There's more for sure, but I've already exceed my TL/DR limit.

Oh--and Gnomeratron VTF--it will do anything you wish for--be careful what you wish for.
