Well, I am sure others will have more experience than me, but I like a smallish light with throw.
I currently have a TK11, and it is very nice. I like the twisty UI, and forward clicky. I would say a good combo of throw and spread.
I have a mag 3d with a terralux tle-300m drop in, powered by a 9aa<=3d sanyo 2700mah's @ 1.2 v each from 5mega. It has good spread and throw.
But my best thrower is my tiablo A9. It has a very narrow beam, but at 200ft, is brigther in its hotspot than either of the others (just brighter than the mag).
It may be I have a great A9, or maybe poor TK11 and tle-300m. I have only just set the mag up so there may be a dead battery amongst the nine, or a poor connections somewhere. Time will tell, but the mag does put out more of a strange shaped wall lof light. More impressive than the A9 for sure, and it certainly puts out way more light, but in the hotspot, the A9 is slightly better, and with 2 rcr123's, it is easier to run the A9.
It may depend on your use. I use the A9 to walk my padocks, checking for vermin, and as horses stay up most of the night, I like to have a very tight beam that I can direct around them when scanning the paddock so they don't lose their night site. It is also way more pocketable, and around $60.
I always wondered what the dereelights would be like though...
