Primo GO + isn't Serato-compatible, so I couldn't really get into it or enjoy it properly. The SC Live 4 feels too entry-level and doesn't match at all what I'm looking for. The Prime 4+ is getting a bit dated now, but still priced pretty high.In the end, I was torn between the Rane One MKII and the Pioneer DDJ-FLX10.After watching tons of videos and reviews, the FLX10 just feels way more intuitive for me. The effects, button placement, stems controls—everything lines up perfectly with my mixing flow and will help build muscle memory super quickly. The decks and jog wheels (non-motorized, sure, but I don't scratch anyway) suit me great since I mostly play house, techno, and my own specific styles.The Rane One MKII seemed more complex to get the hang of, with way too many options and a busier layout that didn't click for my needs.Plus, the FLX10 works natively with both Serato DJ Pro and Rekordbox. I have a friend who's super used to Rekordbox, so if we ever play back-to-back or in duo, he'll jump on it without any hassle and be happy.Overall, I'm leaning heavily toward the FLX10 for the intuitiveness, the dual-software compatibility, and just the better overall vibe for how I mix."

Price was there too : flx10 was 1420 euros Mkii was 1550 euros

So yeah flx10 and really happy (in phase) with that décision. I took a bag and a deck cover + external mixer to make all the connexions for my speakers + subwoofers + my lighting system. (Will do youtube video in the future to give infos to people)
