There is no right answer for this as this might become subjective and relative to the person writing the response. Each of the pentecostal evangelical doctrines have the following in common:
Believe in Jesus as the Savior
Believe in the Holy Trinity (God the Father, God the Son and God the Spirit)
Believe that the Father, the Son and the Holy Spirit are one God
Believe in the resurrection of Jesus Christ
Believe that Jesus will Come again
Believe in the rapture
Believes in the manifestation of the Holy Spirit (Gifts of the Holy Spirit)
I can continue listing them but in the interest of time and space allow me to finish by saying that ALL pentecostal (or other protestant groups) will be marred by DOGMA... there is only one TRUE doctrine and that is what the bible tells us. Anything outside of it is considered DOGMA (personal believes that have been taught as doctrine).
If you are looking for the best pentecostal evangelical doctrine... know this, IT DOES NOT EXIST. However, God will always help you in your personal walk with Him so long as you trust in him. Read His Word (bible) and pray constantly!
Remember, the Jewish people are God's chosen... however, that did not mean they didn't turn to false DOCTRINE/GODS. Salvation has nothing to do with just going to the best PENTECOSTAL church... being a PENTECOSTAL will not save you unless you have a genuine relationship with GOD. A Baptist has the same chance in getting into heaven as any other Christian.
