is700z vs add a suspension seat

I've read some old posts from members saying that the small suspension on the is700z is really about the same as adding a suspension seat to a ztr without suspension.

All you who own the is700z - do you agree with that?

I am considering the is700z but only because of the suspension - I can do without the commercial grade engine, rops, and 3400 hydros - so I can get away with spending ~$1000 less and just add a suspension seat to another model (e.g. Gravely ZTHD or Husqvarna MZ).

I have also seen folks who own is700z shopping for suspension seats...so I'm really wondering if the suspension on teh is700z is really significant or not...or if you have to go to the 2100 to really be satisfied.

Thanks
