Don't forget her record as a senator. Time and again, she fought for equal gender rights and saw to it that workers would be adequately compensated in private business.
Not surprisingly, Arroyo focused on the economy during her presidency, being an economist herself.
The GDP rose in almost every year during her term. A VAT that she imposed helped strengthen the currency. GDP growth plus a strong currency always translate to success, and especially in 2007-2008, the Phillipines could compete with any Asian market. Furthermore, she ratified a trade deal with Japan worth billions of dollars, which contributed massively to the growth of the economy.
I could list many of the 'negative deeds' (poverty rose sharply), but I presume you are well aware of these.
