我们的结论

DreamHost
Choose DreamHost if: you want unlimited storage, a 97-day money-back guarantee, or a US-based host with strong privacy credentials. DreamHost's value at the base level is excellent for simple websites. 97-day refund, rare and reassuring after a bad previous host. On the trade-off side, no classic phone support on many plans. Chat and callbacks only.

我们的首选
A2 Hosting
Choose A2 Hosting if: performance is your priority. A2's Turbo plans with LiteSpeed and Turbo Cache genuinely outperform DreamHost's stack in our speed tests. The Turbo premium is worth it for business sites. Turbo plans near the top of our shared-hosting speed tests. On the trade-off side, no free domain. Buy or transfer separately.
