I've said it myself and heard it from many others that the SR20 is underpowered, which causes some of these issues.
But it depends on what you want to use it for.
Because it's underpowered, it struggles at MTOW and it gets driven harder which does no favours to the engine. Climbs are longer and because it struggles at high weights, it tends to get driven at higher power settings to stop the arse-end from dragging and slowing it down in the cruise.
2+1 pax, a great aircraft. Any more and you'll start to wish you had an SR22.
Was talking to a mate on the weekend, he operates an SR22 out of 350 metres, day in, day out..... there's your difference. An SR20 needs a lot more runway than that.
