It's a tough call. Grindelwald had his own unique magical abilities and followers, while Voldemort was feared for his sheer evil and determination. The winner would likely be determined by unexpected factors or a small advantage at the crucial moment.
It's hard to say for sure. Both Grindelwald and Voldemort are powerful dark wizards, but their skills and strategies might differ.
In my opinion, it could go either way. Grindelwald was very cunning, but Voldemort was extremely ruthless and powerful. The outcome might depend on the circumstances and their preparedness.
