Final answer:
Choose a black hole with the mass of a galaxy to experience more extreme effects. As you approach the event horizon, you would experience significant stretching and spaghettification due to the strong tidal forces.
Step-by-step explanation:
In this scenario, you have the choice between a black hole with the mass of Jupiter or one with the mass of an entire galaxy. If you want to experience the inside of a black hole, it would be more interesting to choose the one with the mass of a galaxy. The reason is that the larger the mass of the black hole, the stronger the gravitational pull, which means you would experience more extreme effects as you approach the event horizon.
As you approach the event horizon of a black hole with the mass of Jupiter, the difference in force on your head and your feet would be relatively small. However, if you choose a black hole with the mass of a galaxy, the force difference would be much greater.
