I am starting fresh with the 2nd edition, should I buy this?

Hi!

I played marvel legendary long time ago, had everything till secret wars 2. Then sold everything, when acquired Marvel Champions, but I miss the simplicity of a true deck builder.

I will be buying the 2nd edition of the core set...but since I am a spider fan, should I buy the 2099? Any other good and recent sets of spider? Or any other set? Apart from the spider family (and friends: ms marvel, nova, iron heart,etc) I like x-Men(97).

I'm not planning to get "paint the town red" or "noir" since it's a bit old, or they still hold up?

Also, is the S.H.I.E.L.D still worth, since this new one will come with the new shield agents?

Thanks!
