I think it's very close, especially for those of us who are practicing Christians and not theologians. I would say though that rather than a supply of grace given to everyone so then they have the ability to truly decide to come to Christ but they might still refuse - I would say that there are enough scriptures that indicate a supernatural and creative act of regeneration. And a regenerated person will believe, not just have the ability to choose to believe. But like I said, in practice, the differences aren't that great. Read Owen's work on apostacy and you will see that his warnings are very similar to how a free will Baptist would preach.
When you say "supernatural and creative act of regeneration" what verses are you referring to. I do not see God saving people before they believe.
I see calvinists use the term regeneration as something that has to happen before one can believe but the bible does not agree with you.
Tit 3:5 not by works of righteousness which we have done, but according to His mercy He saved us,
through the washing of regeneration and renewing of the Holy Spirit,
G3824 *
Regeneration, restoration, renovation, rebirth.
The washing of
regeneration (paliggenesía, Tit_3:5)
refers to the spiritual rebirth of the individual soul.

Joh_3:3 Jesus answered and said to him, "Most assuredly, I say to you,
unless one is
born G1080 again, he cannot see the kingdom of God."
Joh_3:7 Do not marvel that I said to you, '
You must be born G1080 again.'
G1080 *
S
poken of God begetting in a spiritual sense which consists in
regenerating, sanctifying, quickening anew, and ennobling the powers of the natural man by imparting to him a new life and a new spirit in Christ
xxx
1Pe_1:23 having been
born G313 again, not of corruptible seed but incorruptible,
through the word of God which lives and abides forever,
G313 *
To beget again,
regenerate.
It is equivalent to being a child of God (Gal_3:26) or to be born of God (Joh_1:12-13; 1Jn_3:9) or to be born from above (ánōthen [G509], Joh_3:3)

Dave regeneration in the bible means spiritual rebirth which can only come after one believes in Christ Jesus not before Acts of the Apostles 16:30-31 and is when we are sealed by the Holy Spirit Ephesians 1:13
If we held to your view of regeneration before one believes and it being selectively given then would that make God responsible for all those that are lost as without that regeneration they could not believe?
This is just one more of the reasons that I think the calvinist view is wrong.
