I honestly recommend V3 over V2; it has a more pleasing classic to dud ratio and the presentation is slightly better (though I do recommend V2 as well).
On The Extras Podcast, George Feltenstein mentions some interesting comments:
-V4's lineup is already finalized and is expected to be announced later this month
-V4's long announcement/release was due to ensuring the shipment of nitrate from the East Coast (Library of Congress has the nitrate negatives for the library bought by AAP). George's wording makes it sound like more than two cartoons will be newly restored
-Its still 25 cartoons that haven't been available restored on DVD or Blu-ray, with a selection of all decades
-More theatrical animation is planned for 2025, perhaps with more Warner discs and other series (misc. MGM?). George also mentions the heat being turned up on the TV animation, which can be seen now with at least one release on some HB each month. I assume we can expect this to stay the same, but I personally hope its material I'd actually want to buy
