I have to say I think they have a point that many people would "choose" Earth (as if the choice would really be ours to make). The JWs teach that most humans have a natural desire to continue their life on Earth provided it would be under perfect conditions. The Catholic retort to that is that humans only think that because they have never experienced life in Heaven and can't even imagine what it would be like.
I think rebel's hit the "nail on the head" so to speak. There is nothing in scripture (and therefore in christian teaching) that speaks of there being a choice. In fact, there's nothing in scripture, despite what the dubs say with their convoluted arguments, that says there's even two hopes. All the scriptures teach is that those 'in the Lord' will be 'with the Lord' and 'will see his face'. In other words, christians, all christians - not just a limited number of 144,000, are in union with Christ as the NWT puts it. So for a christian, the hope is that they will be "with the Lord" wherever and whatever that may be.
When I was a dub (for many decades) I only imagined living on earth because that was all that was explained to me. Also, I take Ray Franz's point that for us we accepted a "spiritual materialism" and that's how we presented the gospel to people 'on the doors'. We would open a brochure or tract to a picture of some imagined parklike existence with people smiling, kids playing with wild animals, a nice house in the background and offer that to people as being the christian hope. No where was there existence with God. The fact is, it wasn't the Bible hope at all. We were misrepresenting what it means to be a christian - yet ironically claiming to be the "true christians".
Since becoming a 'real christian' (my term) I can see that it wasn't for me to choose but rather it's God's choice and we are either led or not.
Another aspect to this is that the dubs never explain heaven in terms other than it's a place (remember Pleiedes?), What they need to acknowledge is that the creator god also made time and space and so isn't bound by either. What the Bible presents of heaven is that it's with God. Being some kind of paradise in the sky isn't there in the Bible.
