Are 45's really THAT good?

I'm just sitting here enjoying a boatload of LP's I got for Christmas. Good stuff, Coltrane, Rollins, Davis, Krall, Clapton, etc. While listening I was skimming through an Acoustics Sound catalog. I see they sell the same recordings on 45 RPM format. The price is usually around $50 for (2) 45 LP's. I could get the same version on (1) 33 1/3 LP for half the price, sometimes less. My question, to those that have experience is:

Is the sound in 45 RPM format that much better? Good enough to pay twice as much and get up and change sides twice as often?

Happy Holidays,
John
