Honest opinion
If you are buying a used Rocket on Craigslist or eBay, the seller’s descaling history matters more than any other variable. We have seen 12-year-old Giottos that pull better than 4-year-old ones because the older one had annual descaling religiously and the younger one had hard tap water and zero filter. Ask for the descaling records before you buy.
