In the past, Tom's magical abilities were already quite strong even as a young student. His natural talent for magic was evident. However, if Harry travels back in time, he would bring with him the knowledge and skills he has learned in his own time. So in terms of spellcasting knowledge, Harry might have an edge as he knows spells that were not yet invented or commonly known in Tom's time. But Tom's raw power and his understanding of magic from his own era's perspective would be formidable.
If Tom travels to the future, he would find that magic has evolved. Harry, having grown up in this more advanced magical world, would be more accustomed to the new types of magic and magical devices. For example, Harry is familiar with things like the Marauder's Map which uses a complex form of magic. Tom would need to adapt to these new forms of magic. However, Tom's ability to quickly learn and his ambition might make him catch up fast. He might also bring a different perspective on magic that could even surprise modern wizards with his unique interpretations of spells and magic theory.
When both are in a different time period, say an ancient time in the wizarding world, their magical abilities would be tested in different ways. The magic in ancient times might be more raw and less refined. Tom's natural inclination towards the dark arts might give him an advantage in some ways as he could quickly adapt to the more primal forms of magic. Harry, on the other hand, with his strong moral compass, might be able to find a way to use the magic in a more positive and creative way. Their different approaches to magic based on their personalities and experiences would make for an interesting comparison in any time - traveling scenario.
