I own a DP pro and ordered a GZ pro. I would get DP now since this is likely your only chance. It’s very rare to see once come up for sale used. That should tell you something. GZ you can buy a couple years from now.
Don’t let the 3 battle modes and 2 quests make you think the game will get boring or repetitive. Stacking is great on this game and the layout is fun and challenging. The call outs and humor is also second to none.
I’ve watched a ton of streams on GZ and I hope I like it. GZ is mainly 3 or 4 shots on the middle area of playfield. Doesn’t seem like a lot of left and right spinners being a big part of gameplay. I digress
My vote is get DP if you can only get one. You’ll prob be able to sell your used DP at NIB price on 2 years since it’s in such high demand. Then get GZ
