Eagletac D25A2 Mini and Foursevens Mini M2A are very similar lights... Similar modes/spacing, similar twisty UI, similar body/head size, bolt-on clips on both, and both TMK are available only with XP-G2 in cool white. I believe both use PWM. Both manufacturers are well-regarded. I don't think you can go wrong with either. I know that's not especially helpful in making a decision.
If only to be contrary, I'd go with Foursevens... I've purchased a number of Eagletac lights (including 3 Minis in 1xAA format) and a significant percentage of them were defective and had to be returned or exchanged. Buying from reputable USA dealers, that wasn't a big problem for me per se... but still a PITA, and I concluded anecdotally from my sampling that QA on the Eagtac Minis is not stellar. You mileage may vary, and I hope it does.
I've had a much better success rate on Foursevens and Olight purchases in terms of their QA. And if I do get a lemon from Foursevens, I'm confident that their customer service dept will resolve the issue without my having to ship a light to China.
I want to be clear that I'm not bashing Eagletac... I've got 4 of them, and enjoy them very much. I've given several away as gifts, and never heard any complaints. Among other things, Eagletac has great emitter choice and consistency (I can't say that about Foursevens)... but just not on the D25 Mini line.
