I use both, more or less every day. I always take both with me on my daily run because they both serve a different purpose.
The 22lr is great for closer stuff that is within the range you have it set up for, it is cheap to shoot and can be ninja quiet. If I'm working on a property with horses next door etc then I'll be using a 22lr or pcp.
17hmr is a much more useful tool that really doesn't require range calculations or scope adjustments, hits MUCH harder and definitely doesnt ricochet like 22lr does. Anything between 50-200m is a very dead animal within seconds of it being spotted. Mine is a Savage semi auto with a DPT centrefire overbarrel suppressor, I am very commonly shooting multiple animals sitting next to each other without them getting a chance to spook off.
22lr can be used for longer range targets as well for sure but that takes time and adjustments etc where the 17hmr is more or less just point and shoot from 50-200m.
Buy both and be happy
