pvt, i pretty much go 1gate, 1robo then expand then 2 more gateways, its so good vs terran that you dont even have to vary your builds, that much.
pvz you need to vary your builds alot. I like practicing 2gate stalker pressure push. However i have a voidray into expand into mothership into collosus build that can work really well on some maps.
pvz: 2gate stalker pressure(this build becomes really good after a ton of practice, because you get the speedling timings down really well), 3gate expand(most standard build i guess), voidrays are always good because you dont need to go all in with them. 4gate sucks but i guess it can be ok vs some players (kowi somehow got to rank 1 on US using 4gate alot) then there's blink stalker builds which are ok vs zerg.
pvp, my main build is 1gate, 1robo, 2more gateways then a stargate instead of robo bay. This build is a mediumish build that can do well vs most other protoss builds. The stargate can be used to make voidrays to match collosus builds, and 3gate robo first makes it easy to defend vs all in 4gates/dts/blink stalker builds ect.
korean 4gate is a good build pvp, dts are good beacuse non robo builds are becomming more popular, and standard 4 gate is actually pretty good in pvp.
i used like 2 builds in pvt and 4 builds for pvz/pvp. variety is a must in pvp.
