I don't really rate many of the Legend strikers as anything special, Weah was okay but these days the TOTS players should perform way better than most of the Legends, it's only really an option if you want a "cool" factor to your team or need the chemistry links.
You could try TOTS Lukaku? I have him Red and didn't think I'd like him as he doesn't have 4* skills and is a big man striker but he actually just bangs goals, currently has 53 in 50 games all in tough FUT Champions / DKT games, could be similar but better than Gray as he doesn't have skills either.
Of the End of Era SBC players personally I'd say Lahm is the best to go for if you can use him in a team, I'm also tempted to go for Gerrard though, you can use cheap MLS TOTS players at the moment which has knocked his current price right down.
And finally yea I'm one of the few that also likes wingers this year but 5-3-2 is very very effective so much so I don't mind the loss, beast attacking LB/RB's can be had cheap too (SIF Ox or TOTS Telles for instance)
