I would suggest for drag soldering you go up in size on your bevel tips to include 3mm. And if only one, I'd take the 3mm.
I prefer F over M, personally. The spoon/indent doesn't add all that much improvement, IME. It reduces thermal transfer because the copper doesn't come down as close to the tip's surface. And it costs twice as much. And it just sorta... well, when it's really full it works similar to a regular bevel. When it's in the flat to concave area of fullness, it doesn't necessarily even leave enough solder to positively tell you even made a connection under a microscope (unless your board is gold plated). So it's kinda not that great. The window of the right amount of solder is not really much larger than with an F tip of the same size. The 3mm BCF will blow the 2mm BCM away in this regard. And, ironically, if you want to use a really huge blob, which I do for passives and SOTs and the like, the F will be able to control more solder than the M, due to the chrome plating on the sides. John Gammel says "BCF3 is an amazing drag solder tip." The 2-3mm F tips are easy to load with the right amount of solder for IC drag soldering. Just put solder on the tip and then flick the excess away. The big boy 3mm one will then make perfect toe filets for days. You can swipe probably 4 to 8 rows of 12 SSOP/QFP pins without stopping. The 2mm will do only 1 row, reliably, without messing around with more solder. SOIC pins/pads suck up a LOT more solder than SSOP and smaller. So the 2mm will be even more challenged if you use those huge parts.
The 1mm BCF is also hella useful for bodge wiring, dead-bugging, and the like.
I prefer my 888, partly due to ergonomics. But also cuz they have 1.5 and 2.5mm CF tips (in addition to the 1, 2, and 3). Can't get enough of these tips. They are awesome. The difference between a 2mm and a 3mm bevel tip is hard to describe in words. It's frikkin huge. There really needs to be more sizes between the two. I actually want a 2.7-2.8mm CF tip, too. Hakko is dropping the ball, here, having this gaping hole in the selection of the T12/15 tips. I probably use my 2.5 the most. It fits in more spots than the 3. But you have to load it more often.
Personally, I don't use any of the chisel or pointy tips, bent or otherwise. Got 'em. Don't use 'em. The bevel tips are the thing for SMD. The pointy tips would be useful if only I had 3 arms so I could apply solderwire while holding the parts with tweezers.
