Best speed/thrash metal band?

Just got to Exumer and Artillery before me...also, others not mentioned: Heathen, Ulysses Siren, Terror Squad, and Torture Squad.
 
imo the top 5 thrash bands are:

1 Slayer
2-4 in no order Sodom, Destruction and Kreator :p
5 Exodus


@matheuswhatever... 2 years are a long time... my first experience in metal was 3 years ago... still I know slayer and that theyre not death metal...

@Profånity: well Schizophrenia and BTR make 2 for sepu... at least :p

@Dodens Grav: Are you serious with Torture Squad? To me it definetly sounds like death metal...
 
Thrash:

Dark Angel (esp. Darkness Descends)
Believer (esp. Extraction From Mortality)
Sadus
Death
Vio-lence
Vengeance Rising (first two)


I have some different tastes..I'm not very much for the 'big 4' except for Megadeth, but they were very inconsistent in their style to be one specific style of metal (a bunch of power/traditional metal influences mixed in) except for like 2 albums so I can't really list them as thrash in general unless we're talking about the first album and RIP...my opinion, though..

Speed metal:

Helloween (for the EP and Walls of Jericho)
Rage (early stuff)
Agent Steel
 
Speed Metal:

Running Wild
Blind Guardian (first two)
Paradox
Exciter
Helloween (Walls and EP)
Grave Digger
Stormwarrior
Agent Steel
Cacophony
Cranium
Children Of Bodom
Gammy Ray (Speed influences)
Judas Priest (Painkiller and Ram It Down)
Venom
Motorhead
Piledriver
