Which is better, Tang Zhaoling or Tang Ganling?

after his death, Li Shimin, Emperor Taizong, was buried under the main peak of Jiujun Mountain, 22km east of Liquan County, Shaanxi Province, and was called "Zhaoling" in the world. The geomantic masters of past dynasties all said that "Zhaoling is a treasure trove of geomantic omen that is hard to find in the world, and it is a land of Longxing". Tang Gaozong Li Zhi and Empress Wu Zetian were buried together in Liangshan, northwest of Ganxian County, Shaanxi Province, which is known as "Ganling" in the world. Geomantic masters of past dynasties all said that "Ganling has no royal spirit and the conditions of a treasure house of geomantic omen, so why it was chosen here at that time is really puzzling". So in the end, is it "Zhaoling is not a treasure trove of geomantic omen without royal spirit" or "Ganling is not a treasure trove of geomantic omen without royal spirit"? The ironclad facts are as follows:

1. Emperor Taizong was buried in Zhaoling after Li Shimin died (AD 649). "Li Hong, the crown prince of Emperor Gaozong, was poisoned by Wu Zetian in AD 675; Tang Zhongzong Li Xian, the son of Emperor Gaozong, born in 675 AD, was poisoned by Wei Hou's mother and daughter after only five years in office (75-71 AD). Shang Di Li Zhongmao, the son of Li Xian, who was born in 695 AD, was forced to be in Li Dan after only a few months in office (July 71-August 71 AD). Tang Ruizong Li Dan, the son of Emperor Gaozong, who was born in 662 AD, was abolished by Wu Zetian in his six-year reign (684-69 AD), and was transferred to Li Longji in 71 AD.

2. Li Longji (born in 685, the third son of Li Dan of Tang Ruizong and grandson of Li Zhi of Tang Zhongzong), the Emperor of the Tang Dynasty, was buried in Ganling after Li Zhi's death in Tang Zhongzong (AD 683), who was the Emperor's Empress in 712 and the Emperor's Emperor after the Anshi Rebellion in 756, was also the Emperor's Supper when Li Longji was in power.
