AHHH! I need to make a decision quick >.<

Hi! I am currently debating about these 2 plans I got from the same host. Here they are. I will not say the host cuz i mite mess up some kind of rule here :P

1. Free Account
- Unlimited Bandwidth
- Unlimited Webspace
- Ads (25$ a year to remove - Im gonna do it)
- mySQL (5$ one time setup - Im gonna do it)
- CANT USE SPECIFIC PHP TAGS *ie. mail(), system, exec, escapeshellarg, escapeshellcmd, passthru, proc_close, proc_open, shell_exec, chmod, chown, chroot, chgrp, fsockopen, ftp_connect, ftp_ssl_connect, pfsockopen, socket_connect, socket_create, socket_listen, socket_bind, socket_accept, socket_create_listen, socket_send, socket_write, socket_read, symlink, mail, rename, copy*

2. 5$ Plan
- 5GB Bandwidth/month
- 200MB Webspace
- Unlimited MySQL Databases!
- Unlimited Domains / Subdomains
- Unlimited FTP Accounts
- PHP, MySQL, CGI, PERL, SSI
- Protected Directories (.htaccess)
- and others that i dont know what to do with :P

Now, which should i choose? I am going to try to make a virtual pet site for people to sign up, collect money, make their pets stronger, and all that good stuff. Its not a money earning thing for me, its just something fun for me to do (I am such a nerd :P) Thanks in advance.
