 It's a good idea to keep a few types of soldering iron tips on hand to cover common applications and swap them out as needed. The flat screwdriver tip is probably the most common. It's a good choice for through-hole parts and likely your best bet for everyday use. Fine point tips, as you might have guessed, these are excellent for directing heat to smaller joints and surface mount parts. And of course the mighty hoof tip. Great for larger joints and higher power components, the broad flat point transfers heat quickly. Avoid using one of these on anything delicate. A hot hoof can easily trample sensitive parts. Whichever you use, keep it clean and keep it around longer by turning off the power when not in use. Seriously, it's easy to forget.
