As much as I have used and liked the .17 WSM in four rifles to date, I think I would still recommend the .17 HMR. I never had ignition problems (two VQs an 1885, and a Ruger), but the .17 WSM will be louder, and there are not nearly the number of options on rifles. Also, .17 HMR ammunition is so much more common, and you are used to it.
Regarding wind sensitivity, you don't mention to what you are comparing wind drift. The BC of the .17 HMR (and .17 WSM) bullets betters those of any other rimfire ammunition, including the .22 WMR loads, so, the wind drift is less. Other centerfire rounds will obviously be better in wind, but no other rimfire will. The .17 WSM with the 25 gr bullet and higher velocity will drift less than any .17 HMR load, so that may be what you are asking.
What the .17 WSM needs is an affordable but well-built bolt rifle designed specifically for the .17 WSM, like a CZ. That, and more ready availability of ammunition. It's out there, but it is always snapped up. I don't expect it to be discontinued as long as the ammunition disappears off dealers' shelves.
Also, given what I know now, if you can go centerfire (some states won't allow centerfire in certain applications), I think I would look at .17 Hornet. It is a true 300-yard cartridge with many bullet options but not as loud as other centerfires. I bought one of the last Cooper 38s, and it could be the perfect sage rat rifle, considering report, recoil, trajectory, and effectiveness.
