Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for speed. When latency is the product, start here.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
