No, it really isn't.
When the US people go to the polls to vote for a president, they are voting for the President. There might be some oddities in how the votes are counted, as with any electoral system, but there is no doubt about what position you're voting for or who your vote a certain way will help the most.
The number of levels of indirection involved in the election of European Commissioners and the mandates they receive within the Commission is such that there is really no significant accountability to the general public at all. The reality is that the Commission is often full of failed national politicians who have been given a cushy job as a thank-you from political colleagues when they can no longer credibly run for office in their own country. The "we have to do this, it's a European directive that all national governments must implement" technique has become a standard political tool for introducing unpopular legislation that would cause serious political damage if anyone whose job actually depended on being directly elected were to propose it back home.
The electoral college doesn't get to choose any person for President. It's a direct correlation vote: do this, get that result. Such is not true with EC appointments. You vote for a national government, then you pray they appointment an EC that you favor, but there is no legally required direct correlation that says they have to appoint X person. You make that point within your own post (where you note that governments who have chosen unpopular candidates suffer), contradicting your claim that it's just like how the US President is elected.
Yes, in fact, they do.

A lot of people look at it that way, and that's approximately what happens (especially currently), but not because there are any enforced constraints, just because the way electors are chosen gives a very strong likelihood of that effect; historically unpledged electors were a thing [0], and faithless electors remain a thing [1].
1. The citizens vote for a local Member of Parliament to be their representative (the winning MP actually being chosen via the statistically dubious First Past The Post system).
2. The party with the largest group of MPs probably forms the government (except when it doesn't, as with our current coalition administration).
3. The leader of the winning party becomes Prime Minister (except when that leader changes after the election, even if there was an explicit promise before the election that this wasn't what people would be voting for, as with Gordon Brown in the previous administration).
4. The senior executive roles within the government and indirect representatives such as European Commissioners are effectively appointed by the PM and their possibly entirely unelected political advisors.
The idea that European Commissioners have any meaningful electoral accountability at all is crazy. If you don't think so, try this simple test: When our citizens cast their only relevant vote on this matter at the last election in their constituency, was it even possible for them to know the name of the person who would ultimately become the European Commissioner for our country?
More than 50% of MPs have voted for the current UK Government. Yes, they aren't all in the same party. Many countries have coalition governments, and we have no problem with them. A minority government sounds very undemocratic
Right. But that means there is already an average of averages problem, even leaving aside the well documented criticisms of how those MPs are themselves elected. And literally everything beyond that is a matter of political dealing, not representative democracy, so the idea that there is any meaningful democratic accountability at all for the European Commission is still silly.
In any case, we're drifting well off the original topic now and I'm not sure this discussion is going anywhere constructive, so I'm going to stop there.
Except the citizens haven't taken that decision: the unelected European Commission has.
We could probably go down the reductio ad absurdum road of highlighting their appointment by someone who got elected somewhere along the way, but this powerful body is in no way directly accountable to citizens.
Some of the British North American colonials had a popular mantra of "no taxation without representation", which might appeal in this situation.
