I can appreciate that. I guess what I was hoping to prove is that all web hosts are problematic, they all have issues or can cause issue depending on the approach and experience of the customer. What has not worked for you has most likely worked for others.
For example many web hosts, including ones mentioned in this thread, will state that they don’t support Sparkle if asked directly. You just had the bad luck of talking with a support representative who’s clueless, or who has the mandate to upsell everybody to wordpress.
Many web hosts, including ones mentioned in this thread, have bizarre server configurations that will interfere with the website functionality on some level, because their configuration is optimized for wordpress, or assume their customer has enough tech savvy to fix the default configuration.
And I’m not saying I have a great answer, because large web hosts have multiple configurations, depending on the plan, the country, or the timeframe/generation, and maybe some configurations are fine while some are more problematic. Or their customer support depends on which team is active when you contact them. Or their server setup was great at some point but is now overbooked or has questionable technical setup (or viceversa). Sometimes even the love-to-be-maligned godaddy (or the €25/year Italian Aruba) end up in fact working great.
All this makes it very hard to answer “which web host works best”?
It’s a bit of a gamble, and I guess switching once a year is a reasonable strategy to keep costs down and if it doesn’t work out you have to wait for next year’s switch.
