Dom låter alla lika
G12k-100 är en efterföljare till G12k-85.....(eller snarare namnbyte)
"G12M - originally a 25 watt speaker, and currently re-issued as "G12M-Greenback" - Greenback refers to the colour of the plastic magnet cover.
M is the magnet size weight - 35 oz.
G12H - originally a 30 watt speaker, and is currently re-issued also.
H is the larger magnet size weight - 50 oz.
From the G12M the later models with the M size magnet are :-
G12-65 ; G12T-75 - both with the 1 3/4" diameter voice-coil.
Also with the M magnet were manufactured :-
G12-50 ; G12-70 - both with 1 1/2" diameter voice-coil,
and,
V12-80 ; G12T-100 ; Hot 100 -{a current cheaper priced version}-, all with 2" diameter voice coil.
The different voice-coil diameters create a different tone for each even when attached to the same type of cone.
With its 1 1/2" voice coil the G12M-70 -{you wrote you may be able to get}- you will get slightly more emphasized upper-mids and treble than with one of the 1 3/4" or 2" M type alternates.
This will probably suit the types of sounds you mentioned, BUT, part of those sounds depends on the type of Amplifier also.
G12M-70 was a more expensive speaker than "Seventy-80" -{relative to Inflation}, thus likely better made, thus IF the ones you are offered are in good working condition then buy those, but do try them to ensure they work if they are 2nd hand, and that you do like their tone.
Also their 35oz magnet will give a slightly tougher sound than the 30oz magnet of the Seventy-80, but still not too "controlled" such as happens with the H size 50oz magnet models.
Players who prefer the 50oz magnet models tend to like a tight bass sound and controlled mids, either for clean sounds, or for use when a lot of Effects' Pedals are used for various distortions and tone effects.
The M size magnet models give better sustain when simply driven hard by the amplifier than the H size, with-out added pedals, etc ...
The 50oz H magnet models are:-
G12-H ; Vintage 30 ; G12-80 -{now re-issued as "Classic Lead"} ; G12K-85 ; G12H-100.
70, 75, 85s are all related and share some similarities.
G12M-70 - Take whatever good there is in a G12T-75 (fat athoritative bass, articulate highs) and diminish those qualities. Sounds like a weak, watered down, yet more ear piercing 75 IMO. The ONLY worthless Celestion IMO.
