The last time I used maven I found it to be painfully slow in comparison to gradle. Has this improved? I switched to gradle in 2015 and that was a pretty big motivation at the time.
I've used Maven and Gradle since before 2015 and never had that experience. In theory Gradle's caching should make it faster than Maven when it's working right; in practice I found Gradle's slow startup and the number of times I needed to invalidate the caching anyway more than outweighed that benefit. If it's working for you then great.
