update:
its hard to stop GAS-sing for dirt pedals. i havent bought any for the longest time, like 2 years ... i am still sticking to my Zim Foxrox, Love Pedal E burst and Purple Plexi 800 set up... but there are times i would want a higher gain, so theres a slight chance one of the pedals are gonna get bumped for a Wampler Triple Wreck in the future.
as for pedals where i feel like theres nothing that could bump it off, its:
1.) MXR Phase 90 (script) - i feel it is the perfect phaser sound wise, control wise and size wise. others are just hitech stuff with more headache. i have never found the need for another phaser for almost 4 years now.
2.) Red Witch Empress Chorus - after hearing the range of sounds i can get off this thing, i am convinced it is every chorus sound i will ever need. no other chorus on guitar got me interested anymore. it can do shimmery or chorus, and it can even do vibe-lke crazy stuff.
3.) Strymon Blue Sky - i find it hard you could want another reverb pedal when it has all the controls you would need and more ... plus it has the shimmer setting that is like a whole new effect itself
