Linux+ for my first linux cert?

Hi all. I’ll undoubtedly get some “comptia blows” or “certs suck! Get work experience instead!” responses but does anyone have any insight they can share? After 5 years in helpdesk i have finally landed a sysadmin role and intend to work with a little linux down the road. Some people tell me just go for rhcsa but wouldn’t the linux+ be a great initial grounding in linux to start? Also, this of course would recertify my comptia certs, (my company requires an active sec+).
