More complete than Eto'o as a striker/center forward? Yes, I agree with that. Eto'o was not as good with headers.
More complete as a player? Sorry, no. I would love to see Lewandoswki play multiple games as a full winger, he would drop on the pitch like a dead sack.
The same could be said about Ronaldo de Lima as well about headers, though. Is Lewandowski 'more complete' than him as well as a player, then? Of course not.
Lewandowski more pedigree that Eto'o? What do you mean with 'pedigree'?
- Silverware? I hope not, as Eto'o wins easily
- Personal achievements? It depends, as context again is much needed. Mid 2000's was a much higher quality period for football compared to today and scoring numbers were on average not as high as today.
The prime example of this is an average player like Immobile winning the Golden Shoe and scoring more goals in Serie A than Batistuta. Even if he scores 1000 goals, Immobile will never be 1/5 of the player Batistuta was.
Nostalgia bias? I would say no, I rate Lewandowski very highly, simply I saw better players than him. Tell me, did you see prime Eto'o play in 2005? In 2006? Did you see prime Eto'o play in 2011 at Inter? Because I did and trust me, goals alone just cannot describe his skillset, ability and mentality.
If you saw him live, then we can discuss. Otherwise, rather than telling 'Nostalgia Bias, lol' to me, you should work on your football knowledge.
Suarez better than Eto'o? No, to me he was not better. Only 13-14 Suarez approached the levels of prime Eto'o, for the rest of his career he was a step below.
And mind me, I am well aware that he scored more career goals than Eto'o. But then again, numbers without proper context mean nothing in football: he scored more career goals than Ronaldo de Lima as well, still he was not worth half of the Fenomeno.
Peak Suarez > Lewandowski though, I concede that.
