I use Maven exclusively (migrated from Ant about 2 years ago). I've
never had the update problem with NetBeans and a NetBeans-controlled
Tomcat.
For Eclipse, I think there used to be issues. I run Mars.1 (just to
make sure that my pom.xml changes play nicely with Eclipe), and just
tried a small project.
Changes to index.jsp are reflected after a browser refresh.
Changes to CSS are reflected after a browser refresh.
My Eclipse setup for Tomcat uses the defaults, so if you take over a
locally installed Tomcat (rather than running out of
workspace/.metadata), your mileage may vary.
For NetBeans, I have compile-on-save turned on. This means that when I
save a Java file, only that file gets recompiled and added to
target/artifactId/WEB-INF/classes. Tomcat detects this and reloads the
web application automatically.
I don't know if this happens in Eclipse or not. I suppose that I could
test.
If you need / want incremental builds with Maven, you should check out
the Takari Maven Lifecycle plugin
(https://github.com/takari/takari-lifecycle). I haven't yet, but there
are lots of features that look promising (including incremental builds
for resource changes).
. . . . just my two cents
