Two very different fuds but if you were to get me to pick one I would probably opt for something like XLI.
XLC does have some solid companies in there due to what is deemed "communications" like Alphabet, Netflix, Meta etc. But it also has a lot of slower growing, mature companies.
I guess my main idea here is I'd be much more bullish on infrastructure/industrial buildout and expansion than I am the communication sector, if that makes sense.
