I'm thinking Bardem is too high, and that Del Toro is definately too high.
I was kinda expecting Gantz to be number 2.
fair enough, but i'll give you their credentials and see if it changes your mind a bit. for Del Toro (im assuming you are talking about Traffic, not Che, but i'll do both just in case). Traffic gets underrated because its a foreign language performance in its home country- which is home for a lot of this forum too. but along with Waltz's Landa and Heath's Joker, it was the most dominant "supporting performance" in terms of award recognition in the decade. the thing is, its not a supporting performance. in addition to winning pretty much every award possible in the US for supporting actor, he also won "lead performance" from the Screen Actor's Guild. i treat the SAG award, for a list like this, just as important as the Oscars. the Oscars may be the industry leader, but this is an acting specific list, and all the actors in this country got together and said that performance was the best of the year. the only reason he didn't win best actor at the Oscars was because they stuck him in a supporting category and i'm not gonna hold that against him. for the record, he also won best actor at the Berlin International Film Festival. basically, except for the Satellite awards, the dude was undefeated in terms of possible awards.......... then you have Che, which Sean Penn (who won the award that year) said was the biggest oscar snub he's seen. but the Oscars don't matter in this case, because the Goyas (Spain's equivalent to the Oscars) were smart enough to award him best actor in addition to his Cannes Best Actor award.
in terms of relevance, the major awards here are Oscars/SAG/Globes (US), Cesar/Lumiere (France), Goya/SAU (Spain), Lolas/Bavarian (Germany), Hong Kong Film Awards/Critics Society (Hong Kong), BAFTAs (UK), Academy/Blue Ribbon (Japan), Davids/Critics (Italy), Ariel (Mexico), Filmfare/National (India)... also the Asian and European film awards... and to a lesser extent, the Nikas (Russia) and the major awards (forgetting names here) in Israel, the smaller European countries, AFI (Australia) and Genies (Canada). and of course the accredited film festivals, specifically the biggest ones (Cannes/Venice)
as for Bardem, again i'm not sure which you are talking about, so i'll do all three. The Sea Inside couldn't have better credentials. won both major awards in Spain for best actor (the Goya and the Spanish Actor's Union) in addition to receiving the very rare nomination over here at the Globes (only a handful of foreign language performances get nom'd here). plus the Venice best actor win and, the most telling, a European Film Award for Best Actor over Ganz (probably the best year of competition for that award overall, with Bruhl in the mix as well). you can't really do much better than saying its the best performance in its country, best performance on its continent, and so good that it got nom'd in a country it has nothing to do with. as for No Country, not only did he sweep all the major awards here for supporting actor, but in the process he created what will likely go down as one of the top 5 characters of the decade as well. and for Before Night Falls, its possible its too high. but it did win some major critics awards as well as its Oscar/Globe noms and a Venice best actor award.
then for Ganz. he just didn't dominate the way the others did. DDL couldn't lose an award in the US or UK. Mure swept all the awards in Germany, plus a European Film Award, plus even a BAFTA nomination (once again a performance so good that it got nominated in a foreign country). Leung didn't sweep in Hong Kong, but it has since gone on to be the most talked about role of his career- a career that is basically unmatched in his generation. Bardem beat Ganz out for the European award in addition to sweeping in its country. and Waltz won everything he could in the US and UK plus winning a Cannes best actor. Ganz, although his performance has gained acclaim since its release, failed to win at the German Film Awards plus the German Film Critics Association. he also lost to Bardem as i mentioned. he did win best actor from the London Film Critics Circle though. the international acclaim and the lasting popularity of the performance make it worthy of its spot, but i just cant see it being above the performances above it.
