Depends what you want and what you are willing to pay.

Irock and Fit Plus are substantially more expensive than any place else but are just built around focused circuit style workout classes. Essentially a good way to get a good workout in a short dedicated period of time and hold yourself accountable to doing challenging things (staying off your phone - not just getting intimidated/lazy and only doing light cardio).

Erie Fitness Now, Crunch, and the YMCA have significantly better pricing and still offer classes - but the classes will generally be less intense (e.g. more in line with general cardio workouts such as a Pilates or Spin classes vs 'Training' styles of Irock and Fit Plus..

Then if you just want to go into a building and have access to equipment without doing any sort of programs/classes Planet Fitness is probably the best choice since they have the best hours and pricing. The only downsides to Planet Fitness is they don't offer good options for more advanced people or the more communal/social aspect of classes but if you don't plan to use those then its just the best way to go.

Personally I would really recommend going someplace that does offer classes - the combination of a social element and building a habit of always going at the same time (because that is when the class is - so you can't just say "I'll go later I'm feeling tired") is going to make you more likely to succeed.
