It's not even close with Jonna, I don't think. Matthew is on around 15 Championships (including Challenge Cups which, incidentally, if he wins one more he will have the same number as his jersey. Which is astonishing). I make Jonna to be on 9. David Clarke is on 13 in total, including his 8 (!) Challenge Cups.
In terms of the League, Jonna beats all with 4 to Matthew's 3. I haven't looked at Tait or even Shields (or Longstaff / Hand) but in the EIHL era, Matthew is no doubt talismanic.
