Is the good news preached by the wts the same of the apostle Paul?
The answer is in the text.
Galatians 1:6-9 (English Standard Version)
No Other Gospel
6 I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel— 7 not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. 8 But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. 9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed. So what is the gospel? "The grace of Christ"..."the gospel of Christ". Are JWs preaching it? No. For starters, they are preaching the gospel of "jehovah". Here's THE gospel, as explained by Paul.1 Corinthians 15 (New International Version)
1 Now, brothers, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. 2 By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
3 For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, 4 that he was buried, that he was raised on the third day according to the Scriptures, 5 and that he appeared to Peter, and then to the Twelve. 6 After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.
Three verses (3-5) of to receive, take your stand on and be saved, plain and simple.
Blessings,
Stephen
