That would depend on why you don't like the 224. If you like precise brushes the 226 could be a good addition to your brush collection.
For me the 226 works different than the 224 so the chances are good that you would like the 226 even if you don't like the 224.
Can you try the brush at your counter/store? Or is the tester already gone?
The 226 is softer than the 217 but a bit stiffer than the 224 IMO.
