I have a macbook pro 13' (early 15) and my battery needs servicing. Beside the battery message, my mac is in really good condition. Since my mac is aging, would it be more cost effective to buy a newer mac or to just get the battery serviced?

Since your Mac has fast connections (USB 5 Gbps) and fast WiFi (802.11ac) and it is in good shape, if it runs to your liking and you have enough internal storage, you could continue to use it, although it is limited to Monterey so in several years you may find it doesn't provide all the capabilities you might want. (Some software may require a later MacOS soon, some already do in fact.)
I replaced a battery in a 2013 MacBook Air for $79.75 the cost for a compatible battery from OWC plus $55 labor for the task. This battery has twice the capacity as the original one, so it lasts twice as long. I used an Apple Certified Service Provider -- Apple itself won't do work on older Macs like yours but their certified third party providers often will and the cost is very reasonable, in my experience.
A new Mac laptop similarly equipped would cost about ten times the above so if your Mac is working well, I would stay with it. The 2013 laptop I have is still working fine, my only complaint is that it is limited to Big Sur because it is so old.
