I don't think "comforting" is an apt description of pantheism; in fact, it postulating a cold mechanical universe (as opposed to the idea that a God must necessarily be omnibenevolent) is often cited as a criticism of pantheist frameworks.
I find that panentheist flavors tend to dabble more with metaphysical supernatural stuff, but that pantheism is characterized by its rejection of blind belief. Talks about intimacy and experience feel strongly panentheistic to me, whereas a pantheist might instead summarize their position with something along the lines of "the laws of physics are omnipresent and omnipotent, and that's the hard scientific evidence of the conceptual thing you call God"
