Both island's won four and drew two of their respective team matches throughout the day while the previous evening Jersey's players were in top form winning eleven of the 15 Channel Islands singles and doubles titles.
It was a remarkable weekend though one that was later touched by great sadness as news of the death of table tennis stalwart Geoff Reed (89) on the Sunday came through.
Jersey and Guernsey had home-born players in their respective Green teams and the large crowd were appreciative of some excellent play throughout the near four hours of action.
Jersey's Jordan Wykes won his three singles and Josh Band and new cap Chris Morshead contributed two wins apiece, with the doubles a 3-0 win for Wykes and Band.
The Aggregate Trophy could not have had a closer finish as Wykes needed to win the final match, or Guernsey would have retained the silverware as holders, and the 15-year-old player-of-the-match delivered before being mobbed by his excited team-mates.
Jersey coach Craig Gascoyne said: 'I'm astonished; it's been a long day and I can't believe the result and to win the Green Trophy and the Aggregate Trophy like that is incredible.
'The performance of the boys was great; they were so determined and their games now are becoming technically strong.
'They've all got their individual styles and they played out of their skin to win.
'Jordan is such a talent, he is fearless. He comes to me between the games so relaxed and then he goes out to the table again so focused which is great to see.'
Wykes won the opener 3-2 against Josh Stacey, the latter who produced a wonderful top-spin cross-table winner to go 9-8 ahead in the third only for Wykes to take the next three points to go 2-1 ahead.
Stacey forced Wykes into a succession of errors as he levelled the scores before Wykes won the deciding fifth 11-3.
Band was not at his best in his opening singles and he was chasing the game after Alex Robinson won the first two 11-8, 11-9.
Band won three points on the trot to trail 10-9 nine in the third before putting Robinson's low serve into the net for a 3-0 defeat.
Chris Morshead put Jersey 2-1 up after defeating Butler 3-2.
Morshead produced some unbelievable returns with his chopping-style game, one way back off the table to lead 7-6 in the opener which he won 11-6.
Butler won the second comfortably and the match went to five with Morshead winning it 11-7 after two tight serves forced Butler to return into the net.
Band was much improved in his second match winning 14-12, 11-9, 11-6 against Stacey to put Jersey 3-1 ahead. Band's strong back-hand flicks contributed to several winners past Stacey's forehand.
Wykes made it 4-1 after he saw off Butler 3-0. After racing to the first 11-5, Wykes was 6-2 up in the second only for Butler to counter with some good winners to lead 12-11 and 13-12.
Wykes saved game point each time before then forcing Butler into consecutive mistakes to win 15-13 and in the next Butler lost 11-8 after putting his top-spin back hand shot off the end of the table.
All four players hit some glorious winners in an evenly-match doubles won by Band and Wykes 11-8, 11-7, 11-7 against Butler and Robinson, a win which meant Jersey retained the trophy.
Robinson gave Guernsey something to cheer when he beat Morshead 11-7, 11-7, 13-11 but the night belonged to Jersey as Band defeated Butler 11-9 in a deciding fifth, in the best match of the night, and 3-0 wins by Morshead and Wykes against Stacey and Robinson compounded Guernsey's misery.
Jersey's women were defeated 7-3 in their match while in Friday's CI finals the result of the night was Sofia Uddnas and Kelsey Le Maistre coming from 2-0 down to win 11-3 in a deciding seventh game against regular winners Dawn Morgan and Kay Chivers.
