Yeah, i hear you, i took ages to make the move myself, was torn between Atto 3 and MG4, considered a Dolphin together with a HEV for a while, almost bought an Atto 3 but then Seal came along and i knew that was the one for me, no regrets after 1 year.
Sealion 7 would be my choice today.
Starting to see some red plates around already, hopefully you don’t have too long a wait, see some having Feb/March delivery dates !
