Bale is Wales' big hope against Belgium's star-studded team.
Ramsey said: "Belgium is going to be a good test as they have some talented players playing at the highest level.
"But I personally wouldn't swap Gareth for any of their lads. He is always a threat creating and scoring goals.
"He has that quality to whip in a ball or come inside and shoot from distance and cause a problem for the goalkeeper.
"You can't say he has got off to a slow start, he's created a few opportunities in the games I've seen on Match Of The Day.
"Spurs have had a tough start to the season but he has definitely shown on the training field he is as good as ever.
"He has a few hat-tricks, like against Inter Milan when he tore Maicon apart. He is definitely a player who can be the key for us to unlocking defences."
