Hello and :welcome:!
When asking a question like that it's always helpful to give a little bit more info such as (but not limited to) the following:
What will you be using it for?
Do you only want high output or is runtime a concern?
Do you have a preference for battery type?
What type of beam do you like, floody or tight/throwy?
Do you want single level or multiple levels hi/med/low?
User interface (UI) do you want simple hi/low or a complicated programmable UI?
What kind of switch: twisty, side click, rear click, forward/reverse?
How much $$ are you looking to spend?
There are many more I'm sure but, like you said, there are many many torches out there and to recommend one we need a bit more info.
Good luck, I hope you find what you're looking for!
EDIT: something like this is certainly among the smallest/brightest torch:
