The following are brief impressions of various tires I've used since going electric in 2014. I'd almost given up finding a favorite rear tire, but I finally did - the F & R tires directly below are my go-to's now. I ride about 50% rocky-rooty single track, 20% hardpack, 10% loam, 10% shallow sand, 10% street. I used to think I could tell how well a tire would work for me by how it looked & that wider was always better, but not any more.
FRONT: Bridgestone M59 (intermediate / soft, 80/100-21)
This tire tracks EX in nearly everything & wears very well, with EX braking & cornering too. Like the MX33 below, it uses mainly the center knobs only during acceleration/coasting for directional stability and resistance to deflection, with the L/R middle knob sets engaging during impacts / cornering / hard braking after the ctr knobs dig in (the side/edge knobs are mostly for hi-speed cornering & really soft stuff). This tire looks like a skinny joke to me even on the wider rim, but I much prefer it to the Shinko fatty or any of the other F tires below for the riding I do.
REAR: Dunlop MX33 (soft / intermediate, 120/90-19)
After the MX31 I've been unimpressed by Dunlops, so I figured this MX33 would be the last one I tried & threw it on to use it up. OMG, it works great - finally another EX Dunlop! Everything stated above for the M59 applies equally to this tire, except under acceleration the tall knobs instantly dig in and grab everything, with little or no wheelspin in WOT mode 3 (if it does spin, it's a brief burst w/o fishtailing or loss of control). Note the 120/90 size (not 120/80); this tire has a huge OD & was @ 10mm closer to the mud flap, a much bigger change than the spec sheet's .36"/9mm OD increase would indicate. It's also available in 120/90-18, with a slightly smaller OD. Wear seems very good so far.

Kenda K785 Millville II (s/i, soft-terrain dir., 120/90-19)
R: used in 'scoop' mud-tire direction, less traction than MX3S, wears OK
Pirelli MX-32 Pro (i/h, 120/90-19)
R: similar to MX3S, VG traction, stable-feeling, wears VG
CST/Cheng Shin Legion MX-VI (s/i, 80/100-21)
F: VG traction in loam, C skittish in woods, wanders, light track tire, pressure critical (16psi), wears OK
Bridgestone X30 (i, 120/90-19)

Michelin S-12 XC (s, 140/80-18, 90/90-21)
R: OK m/s/t, NG i/t: spins, drifts around, skates in C, better after ctr knobs worn, wears OK
F: NG in i/t, OK m, dry / hard / street C squirrely, pointy/grabby side knobs, pressure critical, wears OK
Motoz Terrapactor S/T (s/i, 120/90-18, 80/100-21)
R: VG a/t s-l traction & s/t s-l braking, skaty / power-slides in i/t C, wears G
F: VG s/t s-l traction/braking, poor grip in i/t C, grabby side knobs, pressure critical, wears G

R: VG+ traction a/t, tracks straight / corners well, wears G
Dunlop MX32F (s/i, 80/100-21)
F: EX traction a/t, tracks straight, wears well, pressure fairly critical
Still a bunch of tires on deck (M5B, X-20, Gauntlet, Dirt Hoe, XCMS, GT232N, etc.) waiting their turn.
