Any software available on the Mac is available on the PC, and, you will find, there is more software for the PC than the Mac.
Does a Mac run faster?
No, Macs have limited compatibility, thus, preventing a wider range of software and hardware from being available. Due to this lack of compatibility, you cant load as much "stuff" on it.
Do Macs have better hardware?
No, you can build a PC with the exact same hardware (except the motherboard), and it will be greatly cheaper.
Is a Mac more secure?
No, Macs have a very small market share, therefor, they are less targeted for hacking and virus creation. A PC is more targeted for hacking and viruses, but, protection is easy to find (Avast Antivirus, and built in Firewall, both free), and that issue is quickly resolved.
Why does it seem like PC's are slower?
A lot of people put junk on their PC, as in, they go online, and start uncontrollably installing stuff. (Macs lack free software, so you dont see this as often, but that does not make it a good thing).
Also, since support for older PC operating systems last longer, you will find that there are more people still using older computers, simply since they keep working. (Older Mac systems will quickly become completely incompatible with newer software)
The Mac vs. PC argument will exist until Apple goes out of business, or until we all go over to Linux.
PC's have a wider avaliability of hardware components. Macs are limited to a few selections.
