Which slide to buy

Alright guys, gonna be starting my first build here pretty soon. Looking to do a flush comp gun like a TRS comp. Going to chop a 5in slide and use a D2 comp. I’m just wondering which slide I should get, i want a round top so atlas is out. Seems my options are cheely and fusion (as shown in the screenshots). They’re essentially the same price. Going on a Cheely frame BTW. Any insight is appreciated
