I need help with choosing a LAMP and WAMP server to learn, practice PHP/SQL. The STACK. Any suggestions out there...?

LAMP would be cheap to use.

I agree with veerain LAMP is the way to go.-:)

CentOS 7.1
Apache 2.4
MariaDB
PHP
PhnMyAdmin
Perl
Awstats

your choice of CMS
( i prefer "geekLog" but there are many to choose from if you use one )

LAMP.

For learning purposes, you might want to check out XAMPP. It works like a charm.
