I'll say in advance that I would probably take all of these strikers, but I don't see how you can downgrade Lukaku when these three in bold have yet to prove what Lukaku already has in the PL, that he is a goal scorer, especially Origi.
The jury is still out on Bony, in my opinion, but I doubt don't that he'll be decent enough. I'd still rather have Lukaku because of his age and the fact that he won't be at ACON.
Remy is the only one in that list of options that I could see replicating his form over the last two seasons, but even then, I think I'd want Lukaku just because of his sell-on value if it doesn't work. I also think Remy is a bit of a mercenary and his reputation isn't the greatest for what we usually expect at Everton.
