Here is a list of the major speedsters for both companies. Each Hero has a link for more info.
Please note that both the companies that now make up DC (Quality and DC Comics) came out with speedsters a year before Golden age Marvel (Timely).
Also note that Barry Allen Flash pre dates Marvel's Quicksilver by 8 years.
Also note that public domain took the ability for DC to use the Quicksilver name which it had rights to since 1940 when Marvel Debuted Quicksilver in 1964.
Also note that Johnny Quick and Whizzer have evil versions on alternate realities of their respective universes.
Without further adieu, here is my list of the major speedsters in DC and Marvel.
