Oh i2P is definitively a better option where you can have it. However, Tor is somewhat more approachable as of current: we have for example Tor Browser for the masses, whereas I at least haven’t heard of any sort of “I2P Browser” at least for Firefox. Of the three options, Tor is the only one I know that is “portable” (you don’t need to be able to make admin-level network changes to use it).
