Rega Planar 3: Is the Exact a significant upgrade from the Elys 2?

I understand that not everyone loves belt drive turntables or Regas but I have an opportunity to buy a new Planar 3 with the Elys 2 for a really good price or a new Planar 3 with the Exact 2 for a few hundred more.

Is the Exact such a significant upgrade over the Elys that it’s worth paying $300 more for a table with it? Or would it be smarter to get the cheaper one with the Elys 2 and choose another upgrade path for the cartridge in the future?
