I had a couple trips to Europe earlier this year, and initially I was leaning towards Airalo but I ended up picking KeepGo because the free 2GB if you buy 1GB+ eSim seemed like a pretty good deal. I'm not a heavy data user (mostly try to stick to wifi) so the 365-day expiration and "valid forever if refilled at least once a year" sounded appealing. Used in Netherlands, Belgium, and France with no complaints (well, other than FT blocks an entire Internet ASN but they fixed that).

Based on that, picked up a separate KeepGo product for Canada. This wasn't quite as useful since I was in Newfoundland, and service was limited to areas that correlated with the Rogers service map (I expected this going in though, based on the network list on their web site). I'm going to Vancouver later this year though so will get more use out of it there I'm sure, plus the one I selected also covers parts of Asia and UAE. The website makes it pretty easy to filter by plugging in whatever country names; some of the products seem competitively priced depending how much you buy, some aren't.
