Is the European School of Economics more well known than Huron university USA in London?

Generally speaking, no. Huron University is not well-known internationally, and even within the US, its recognition is limited. The European School of Economics (ESE) has a somewhat higher profile due to its multiple campuses and marketing efforts, although it's still not considered a top-tier institution globally.

However, "well-known" is relative. Within specific niches or regions, either school might have a higher level of recognition than the other. But overall, in terms of global reputation and recognition among academics and employers, ESE likely holds a slight edge, though neither would be considered highly prestigious.
