WO’s UL 5 day split vs Jeff Nippard essentials

I’m in my first year of taking lifting seriously. Cut down from 215 to 170 last yr and started my first bulk about a month ago. Finishing my first WO generated 4 day UL (45-60 min) next week and want to switch to 5 day. Was planning on just having program generate UL 5 day (45-60 min) but wondering if buying and importing Jeff Nippard’s essentials program 5 day split would be better use of time? I’m pretty lean so I want to build muscle. Any advice much appreciated.
