the xenics titan ge air is so comfortable that it makes me regret the last years of mice i've bought/tried.
an important caveat is that its mouse feet (+ the replacements that ebay buyers tend to bundle with it) are very low quality & will likely be dented, bulged, and/or peeling off the mouse. also, if you fingertip grip by holding the back end of the mouse, you will be holding onto the holes of the honeycomb. thankfully, there are corepad skates for the mouse & the coolermaster mm720 grips and/or truegrip's mm720 grips resolve any comfort issues trivially.
i have to change my hand grip depending on what i'm doing -- fingertip when vertical aiming is equally important to horizontal, and relaxed finger/claw/palm for endurance aiming or horizontal-only aiming -- and this is the only mouse i've ever had that lets me switch between them on the fly without cramping up my ring and pinky fingers.
there are merits to going with a mouse that purely maximizes fingertip grip, like the gwolves hsk plus and pro (still reserving judgment for the m2k that i'll receive at some point before the heat death of the universe), but i believe it's difficult to maintain good performance, or maximize horizontal precision when necessary, with just fingertip. and while they "helped" me in some aim training scenarios & could be used for precision aim, they were never comfortable to play with for any period of time, especially if you're actively moving/using a keyboard + flick aim + lift up the tiny mouse frequently to readjust. if it isn't comfortable for your pinky and ring to be tightly pressing together, if your pinky needs relative elevation to your ring finger, and/or if you're not used to a "1-3-1" grip to circumvent the aforementioned ergonomic problem, stay far away from small box mice.
to note, the gwolves hsk pro 4k does come with a variety of grips, including these dot-shaped grips meant to be stacked on top of one another to serve as a makeshift pinky rest & alleviate some of the ring-pinky strain, but the adhesive sucks & by the time you've adjusted them to figure out something that "works", it'll likely be peeling off already. i never really felt confident using my pinky as an anchor point on the makeshift rest either, due to its give/flexibility vs the firm side of the mouse.
also the wooting 60he is the current GOAT of gaming keyboards.
