Epi's Alnico Classics are somewhat notorious for lack of definition and poor ability to cut through in a mix. IMO any of those sets is likely to be a noticeable improvement over the stock Epi humbuckers.
I was going to add my voice to the others and say you can't go wrong with the Duncans. But if only the Toneriders are readily available, my advice would be to choose on of the A2 sets. I believe the ACII Classic neck pickup has more scatter than the Rocksong neck but I'm not 100% positive of that. ACII bridge should have a more vintage character that the Rocksong bridge, which would likely have more drive and mids but a bit less chime and sparkle than the vintage wind.
Full disclosure, I've never owned any of the Tonerider humbuckers myself.
