Series ranking hot take.
Tamers > Data Squad > Adventure > 02 = Frontier > Tri > literal shit > Xros Wars
I haven’t watched Applimon so can’t comment on it. Adventure 2020 is good so far except for some animation issues (but it's not like the old shows were free of that either), but it's not enough to judge just yet.
02 had a lot of writing problems in the second half so I can't rightly call it "good", but it’s definitely the one I have the most nostalgia for since it’s the only one I had VHS tapes of as a kid. I watched them on repeat religiously.
