Well, the answer is…….yes and no.

.22lr firearms can be fussy. As a rule the higher priced .22's will shoot better than CCI-SV. But not always and different brands of the "good stuff" will shoot real well in one gun but not the other.
Rimfire benchrest shooters spend a lot of money finding just the right ammo for their rifles, then order a case of it.
If your shooting at 50' bullseye match with a pistol only you can decide if the extra cost over a season is worth the extra $$.
Good summary, .22 ammo shoots differently from different guns/barrels, it's a trial and error effort. That said, I've found some brands shoot consistently better than others in a variety of .22 guns. And, the awesome thing is when you find that .22 that loves a particular inexpensive.22 ammo!
I used to do rimfire benchrest rifle competition. In my experience, what the match ammo delivers is more consistency from round to round. Once you've got your rifle dialed in, in terms of accuracy (the right action, trigger, barrel, tuner etc.), figure out how to shoot with wind, and find the right rifle rest and scope, the wild card to the game was always if you'd run across a "flier" during your string of shots.
The expensive match ammo shot better and had fewer fliers than the less expensive fodder. Eley Tenex and Eley Match were the standard. When we found a brick that shot consistent, with little to no fliers, we'd look at the lot number on the box and figure out what particular machine that ammo was made from. We'd then connect with the specialty ammo distributor/retailer that could get that particular ammo, and order a couple of cases of it. All around, it's an expensive proposition.
All of this said, OP, do your shooting needs with your pistol sound like they match up with this level of attention and expense? If you're doing bench rest pistol competition, then probably. There's a lot to gearing up, equipment wise, for rimfire pistol competition. Those guns can really see the benefit of match .22 pistol ammo. If you're not going down that road, and looking to just shoot your 17-2 well, I personally wouldn't mess with it. There's a lot of good, accurate ammo that will work very well, you just need to experiment a little bit. I love my 17s, and have never had the need to feed them the super premium ammo. I've found CCI SV is pretty consistent, as is SK, Norma, and Wolf. I've also had good luck with Aguiila. YMMV...
