The number of items available on Aliexpress seems far smaller than eBay. And the overall shopping experience on Aliexpress is kind of miserable, worse than eBay.
I think selection and misery depend a lot on what you shop for.
Looking for LoRa modules, eBay has 10 times more items, but half of the sellers are list the same item 30 times with different price and shipping costs, so that is actually reduced offer and enhanced misery. On Aliexpress you rarely find dupes from the same seller, they keep that shit at bay.
