even though I'm mainly a big bore guy... seems I have more than my share of 17's... so I'll comment on a few I have...
smallest... 17 Mach 2 ( 22 LR, necked to 17 ) love this cartridge, shoots like a laser ( head shoot pidgins & squirrels from 100 + yards ) little chance of ricochet for use around the farm, but still powerful enough to easily drop a raccoon out of a tree
17 Hornet... mine is actually a 17 K Hornet, 10" Contender barrel... used to hate this cartridge, had to size 22 Hornet cases, then fire form to 17 K Hornet... my buddy has a 17 A.I. Hornet... pretty much the same loading issues... however the new 17 Hornet standardized from Hornady fits into my chamber ( but not my buddies ) & if used as a fire form load, is plenty accurate in my chamber the 1st time, then easy to load as a K Hornet after that... Hornady has given my Contender barrel new life... as far as "power", I don't think the Hornet has enough over the Mach 2 ( or 17 HMR ) for most to mess with, unless you like "rocket science" ( reloading ) as much as I do...
17 Fireball... Remington really dropped the ball on promoting this round, as someone that shoots 4 different 17's, this one is the most balanced of all the 17's IMO... it has become my 2nd favorite behind the lil Mach 2... much more powerful than "existing" rimfires, easier on barrels & much more efficient than the bigger 17 Remington
17 Remington ( 223 case ) my FIL loved this round, & shot it enough to shoot the throat out of a Remington 700 rifle ( which is the gun I converted to 17 Fireball ) he had loads chrono'd over 4,000 fps, & several loads you could see the streak of the bullet disintegrating on the way to the target... it's the king of speed here, but, while I still have a Contender barrel in this caliber, personally my least favorite...
as far as the Savages... I don't have a good one, but have heard from several people, as far as newer guns, they are as accurate as any... I'm sure Hornady will ( & is already ) doing a better job promoting the 17 Hornet, than Remington did with the 17 Fireball
however, if I were buying one 17 caliber rifle, based on cartridge alone, I think I'd still pick the 17 Fireball, but this is based on the fact I reload... if I didn't reload, I'd be wanting to see more on that "super rimfire", before I decided between it & the 17 Hornet
