S2+ or Solarforce L2x both 10-20
My current EDC gets the most use: Supfire S1 host, shaved Nichia 219C on Noctigon, FET-modded AK47-driver, two-led lighted tailcap. All in all 30-ish dollar.

CNQG brass beauty (20$~)
XML2 T6-4C (3.50$~)
1520mA KD driver (4$~)
45° TIR optic (1$~)
So, yeah about 28$
BLF Special Edition Manker A6, $25
I’ll vote when I finish making it.
20$ to 30$ for the blf x6 se with xpg2 s2 1d (dedomed) on noctigon and fet + 7135 driver = pocket thrower
BLF A6 SE, 18350 prototype tube, XPL-HI V3 2B- about $35 total…
SIPIK SK68 edc stock. Around the house Yezl Y3 2×26650 with resistor mod and noctigon XML2. Wife loves the SRK for the pantry.
Favorite is such a hard word to apply to flashlights, at least for me. I’ve got lots of lights and like them all for different reasons. If I was forced to choose just one light and had to get rid of the rest, I’d probably keep my SC62w. Its very reliable, flexible for different situations, full of smart stuff, and has the best ratio of power to portability. Its probably my most-used light, but does that make it my favorite? I don’t know.
The SC62w is not the light I’ve been carrying every day lately. That honor (at the moment) goes to my 3x XP-L on a FET+1 in a BLF/ReyLight Ti host. I think its just beautiful and is also a very capable light, plus if something went wrong with it I could actually fix it (unlike my Zebras), but does that make it my favorite?
Then there’s my TN35 - too large to carry comfortably for long periods of time but its just so much fun to use when I need a lot of light. Or my M3SX for when I really need to throw…
I could go on. I don’t think I’ve decided what my favorite light is, but looking through the list I just created I do see a pattern - they’re all over $60 invested, so its easy to cast my vote.
$25 for the Manker BLF A6. It’s my favorite because the Raccoon likes it. 
But, seriously, if I had know ahead of time it would be so awesome, I’d purchased 20 instead of 2.
Most used? $30-40 for the Olight S20 (L2)
Favorite? $190-230 for Supbeam X60 depending on whether you include batteries
EE A6 head and switch $20, BLF X6 body tube $20, MTN-17DDm + 7135 board $14 ,XPL triple notigon $20, optic $3, spacer cut from $20 Copper rod.
I do have a X6 with a a6 body tube and 11.5” of copper left over though.
2 Favorites, both used daily
My Texas Poker hangs on a Titanium curb chain around my neck, where it’s been in use for almost 3 years now. Cost—-about $800
My Titanium X6 from WeLight is carried on my belt, fitted with 4 Nichia 219C and 11 tritium vials it comes in around $320
Neither of these were options on your list…
My favourite most used light is custom titanium Sinner 18350 Tri-EDC with Nichia 219B. It cost me around US$260 including DHL shipping from UAE.
It’s my EDC light inside my sling bag, my bedside light to check on my baby boy diapers and I’ve dropped the light and it has some scratches due to everyday use.
Upwards of $100 — because I count “most used” time accumulated starting back when dinosaurs roamed.
That would be an Arc LS with tubes to use CR2, RCR123, or 2xAA, and modified with an amber Luxeon and a custom driver
EDIT — the driver is Goldserve’s FLUpic. Many, many options. Mentioned at Found a Tri-Flupic Driver in my drawer, what to do with it?
Maratac copper AAA, my keychain light and most used.
L10 ~$20+
I bought two as well. :)
I think that they're a lot better than my old favorites, the Convoy S series.
I also think that two is enough for me. ;)
TX25C2 with a 22mm FET E-switch driver with Moppydrv modes, upgraded thicker wiring, a bit deeper reflector, XP-L Hi V3 in 1C tint on copper MPCB, polished clip and steel crenelated bezel My EDC! Love it!
