Reylight are good quality and small - I have the aluminium LANapple with a nice warm nichia LED. They do some exotic materials at crazy prices. The LANapple often goes out of stock in the ‘basic’ aluminium versions though.
Given are surprisingly decent for the price.
Nitecore are have good performance but always a fairly cold tint to help maximum brightness figures.
Loop Gear have a nice 14500 (same as an AA battery in size but over double the voltage and higher current rating) light, the SK03.
Cheap as chips option but still pretty well thought of are Sofirn.
14500 battery is a good format that all the above offer. The torches tend to still work on any AA size/chemistry so you’ll never be short of battery choice. They are a tad dimmer on the 1.5v but only compared to the insane brightness they have at 3.7v. Nice compact form too. Just make sure you get one where the battery can be charged via an inbuilt USB-c socket (either in the battery itself or the torch, although that adds size and can reduce waterproof rating), otherwise you need a dedicated charger.
If it’s mainly close up work then the warmer tint LEDs are best - nichia typically, as they render colours better so you can tell your dog poo from a twig. If you need throw the colder tints fair better but you’re not going to spot a dog poo vs a twig if you stand that far away.
