mdma is always nice but you can't beat a good pill, regarding which is the smarter choice the mdma will probably be more cost effective and have less chances of impurities given pills often have other substances, binders etc. A lot depends on your preferences really, if you know its a good pill, has been tested and is known not to contain any nasties and a high dose of mdma then that might be the way to go or just but the md and cap it up, either way you will have a wonderful time I am sure.
