Actually, this question depends on whose fighting style you prefer.
Rommel, the Desert Fox, to be honest, what he is best at is blitzkrieg and mobile defensive warfare. In France, His 7th Armored Division marched forward and was invincible, known as the Devil's Division. In North Africa, he made two unexpected attacks, running thousands of miles, and similarly, he retreated thousands of miles twice without any damage (not counting the Italian army). And he was defending. His achievements in the field of warfare were no less than his offensive operations. Later, he moved to Italy and the defense of Caen. It showed the strength of his defensive warfare, so much so that Montgomery was helpless under the city of Caen. It can be regarded as Rommel's revenge for El Alamein. Later, when the Allied ground forces commander, the later famous Bradley, heard the news that Rommel was dead, he couldn't help but let out a sigh of relief. It can be said that if the Atlantic Wall had been built by Rommel two years earlier, , it is estimated that when the Allied forces landed, they would only encounter tough enemies like the "Omaha" beachhead. Or if Rommel was given 6 German motorized divisions or armored divisions in 1942, he would definitely be able to capture the entire Egypt. By then Britain will definitely surrender, and the European outcome of World War II may be about to change.
Montgomery, a master of positional warfare, fights steadily. In fact, I don't like his style very much. His fighting style is typical of British soldiers. He would not start any combat operations until 100 supplies and personnel were in place, and even very few exploratory attacks were carried out. Moreover, he fought for power and gain with little ambition, which triggered many conflicts between the British and American political circles in 1944, and he always wanted to Commanding more American troops, Eisenhower twice planned to fire him and tell him to go home. (If Lao Ai really submitted this proposal to the British and American Chiefs of Staff meeting, then the meeting would definitely support Lao Ai.) However, it is undeniable Montgomery's positional warfare was precisely the nemesis of Rommel's blitzkrieg. He used his powerful numbers, tanks, planes, and artillery to defeat Rommel's attack on Cairo, but it was precisely his dilly-dallying offensive tactics that failed him every time. Let Rommel escape, so that although he had a strong force, he was unable to completely wipe out the enemy. Finally, under the city of Caen, his powerful attack but ink-stained fighting style was defeated by the flexible Rommel with a small number of troops. He fell into disgrace, was completely humiliated, and was ridiculed by the Americans.
If you talk about me, of course I prefer Rommel, hehe, he is loyal to love, responsible to the country, and can also treat the leader In terms of loyalty, he has more personality, boldness, legend, and tragedy than Lao Meng. He is very similar to Hannibal. His tactics and ending are all similar. In any case, he is a great marshal.
