Probably neither.

God is sovereign, but man has free will.

Does anybody know if Arminianism has a handy acrostic like TULIP? And if not, does it least have a list of basic tenets?

Yes it is somewhere in the middle. 

Here's one of many sources, it is a reformed source, summarizing how the two compare:

                         http://www.the-highway.com/compare.html

The five tenets of Calvinism were established after the five tenets of Arminianism were created.  The followers of Calvin established TULIP after his death in response to the Armianian tenets.

A better question to ask, ISTM, is which belief generally, if not in its purest form, aligns more closely with scripture.  I, of course, being in a minuscule minority here, believe Calvinism does.

Calminian is much closer.

FTL

I have studied Cal and Armin for several years, and both sides have problems. If you go back to the original beliefs of the first and second generation of Christians, their end-times perspective was pre-millennial. But Augustine put a the kibosh on that and the church for 1600 years was dominated by millennial (no literal earthly millennium) ideas.
If one starts with a literal future 1000 year Messianic Kingdom, and takes the references to the kingdom of God/kingdom of Heaven to be a literal Messianic Kingdom, and not everlasting bliss in the clouds with God, you might see that most of the warnings against gross sins are about born-again people losing out on participation in the next part of God's program, the seventh-day rest, the Kingdom of Christ.
If this is a correct understanding, I would agree with Cal. that true believers are secure in their salvation, but they may lose their psuche-life for the duration of the coming age. Only those who persevere will receive the double inheritance of the first-born son, life in the Millennium reigning with Christ, and the common salvation of the eternal ages for all who have received Christ.
If general (spirit) salvation (from the lake of fire) is solely by grace through faith, then election can be based on God's foreknowledge of our faith in his Son. And since faith is non-meritorious, and good works are neither required for salvation nor a necessary consequence of being born-again (can I get an Amen from the thief on the cross?), election in time can be compatible with man's free will.
As for Total Depravity, our spirit, soul and body were all affected by the fall.
Election to salvation (of our spirit) in Christ is based on foreseen faith, and is not unconditional.
The Atonement had adequate provision for all, but is only effective on the repentant soul.
Grace is resistable.
All who receive Christ are saved to the uttermost and are saved from the lake of fire. Saints who persevere in doing good will be rewarded with rulership (inheritance) in the coming kingdom. (Rom 2:2-11) Those saved who are disobedient will be shut out in the darkness that is outside until the kingdom is given back to the Father. (Matt. various)

Salvation is a free gift received by faith. Life in the Kingdom of Christ is a reward for obedience after faith.

Hey, that's cool, Sherman!
