For me, it depends on the purpose of the trip.
Travelling overseas, definitely flying. Cruise ships take forever to get anywhere from here. Smaller cruises (eg South Pacific, NZ) maybe, but I'd rather get there quickly and spend more time at the destination. The transporter sounds ideal! Beam me up, Scottie!
Having said that, I've booked to do a 15 day cruise of the Danube next year. It sounds like a nice gentle cruise, plenty to see, plenty of stops, rather than days of ocean.
I've only once taken a long train trip, and I didn't particularly enjoy it. I've done enough long-haul bus trips to know they're not for me.
Trips around Australia I've done via motorcycle and car. As I mentioned, it depends on the purpose.
Long bike trips are wonderful, but you're limited in luggage, and weather can be a big factor in the enjoyment. For some reason more people want to interact with you (every man and his dog wants to stop and talk about your bike and his old BSA/Triumph/AJS he had back in the 60's...) I remember once, sitting on a bench at a lookout over 3000km from home, with the ex, and I heard a voice behind us say "Well, I'm not going to offer to swap, you know!" It was a very elderly man on a mobility scooter, looking at the bikes.
On a bike, the ride is the purpose as much as the destination.
Car trips are great too - no luggage worries, you can buy as many souvenirs as you want, no worries about rain... But they're a bit more isolating than bike trips. You're just another car on the road. There's the same advantage, though, of being totally free to stop wherever takes your fancy.
