I disagree with the Ayuso comparison.
Ayuso DNF'd 2 out of 4 GTs. Didn't complete a GT last year and it seems he won't complete one this year. (Not looking great for him tbh).
Almeida DNF'd 2 out of 8. He completed a GT every year, even with the DNFs.
Even with a bad day, his worst is a 9th and it was the second GT he did that year. Almeida is way better.
I'm not exactly an Ayuso fan, but honestly, that comparison is unfair to Ayuso.
Almeida is older and they've allowed him to do two GTs in a year; Ayuso has never had the opportunity to do two GTs yet.
From there, another conclusion can be drawn: that Almeida, despite having had more opportunities, hasn't been able to win a GT or finish second.
If Ayuso hadn't gone to the Giro, and seeing that Del Toro finished second, it would have been said that Ayuso would have won because Del Toro was Ayuso's domestique at Tirreno Adriatico.
I don't see any reason to think Almeida would have won this Giro. Winning three one-week races? Simon hasn't won any stage this year and won the Giro. Sean Kelly won multiple one-week races and couldn't win a Giro.
I see Ayuso and Almeida at a similar level in GT, so I can't conclude that he would´ve won the Giro, because so far neither of them has proven to be more capable than the other of doing so.
In any case, his ceiling as a GC leader seems to be similar.
Almeida, despite having done more GTs, hasn't won any either.
When it comes to talking about how he would fare outside the UAE, I don't see any difference. As the leader of another team, he wouldn't aspire to anything more than what he'll achieve this year in the Tour and Vuelta behind Pogacar and Vingegaard.
And he himself said he didn't want to return to the Giro after so many years.
