To echo other posters here, I used to find the A321 much more forgiving in flaps 3. What you can't do with a heavy one is land it like some people land a A319 or A320, with the last minute flare. This will catch EVERYONE out one day regardless of experience and while it's merely embarrassing on a 319 that you've buried into the runway, the increased length and inertia of the 321 will chance severe damage or a tailstrike. Landing the 321 properly will also help you transition to heavier types in time which (trust me!) do not tolerate "snatch" flares.
Stable at 100ft is the key.
I agree with Hans Brinker, BTW, great advice.
