If you own one of these devices and want the best case in 2026, this guide gives you the direct comparison: which case type is best for each device, what Gorilla Cases offers for each, and what the key differences are between them.
Quick Verdict: Best Case for Each in 2026
The best Galaxy S20 Ultra case in 2026 is the Gorilla Cases Galaxy S20 Ultra Waterproof Case at $41.00 — prioritizing IP68 waterproofing for the 108MP Space Zoom camera system.

Device-by-Device Breakdown
Galaxy S20 Ultra (2020): The first Samsung flagship with the 100x Space Zoom periscope lens. The primary case priority for the S20 Ultra in 2026 is waterproofing — the factory IP68 rating has degraded with years of use, and the camera system is too valuable to risk water damage. The Gorilla Cases S20 Ultra Waterproof Case at $41.00 is the definitive answer. For a belt-carry working environment, the Galaxy S20 Ultra Military Grade Holster Case at $43.00 is the alternative.
Galaxy Note 20 Ultra (2020): The final Samsung Galaxy Note device. The S Pen is the defining feature — any case must preserve S Pen slot access, which the Gorilla Cases Note 20 Ultra Waterproof Case does with its dedicated S Pen cutout. The irreplaceable nature of the device (Samsung has retired the Note line) makes waterproof protection the top priority: an unfixable water damage event on the Note 20 Ultra cannot be replaced with an equivalent device from Samsung. At $41.00, this is the most important case investment in the three-way comparison.
Galaxy S21 Ultra (2021): Samsung's first S-series flagship to support the S Pen, with a 108MP quad camera and a 6.8-inch curved AMOLED. The S21 Ultra is the newest of the three devices and closest to current flagship performance. The leather wallet case at $39.00 is the best choice for users who want to eliminate a separate wallet while protecting the device. For users who need drop protection above wallet functionality, a military grade or holster case is also available in the Gorilla Cases lineup.
Camera Comparison: S20 Ultra vs Note 20 Ultra vs S21 Ultra
All three devices have 108MP main sensors and 100x Space Zoom capabilities. The Galaxy S21 Ultra adds a quad-camera system with two telephoto lenses for improved zoom performance at different ranges. The Note 20 Ultra and S20 Ultra use the same periscope telephoto architecture. From a camera protection standpoint, all three benefit equally from a case with a raised camera ring and clear optical window covering all lenses.
S Pen Comparison: Note 20 Ultra vs S21 Ultra vs S20 Ultra
The Galaxy Note 20 Ultra has a built-in S Pen slot in the device body. The Galaxy S21 Ultra supports the S Pen as a separately purchased accessory (no built-in slot). The Galaxy S20 Ultra has no S Pen support. For Note 20 Ultra users, S Pen slot access on the case is non-negotiable. For S21 Ultra users with an S Pen, the S Pen is stored separately, so the case does not need a built-in stylus slot.
Display Comparison
Galaxy S20 Ultra: 6.9-inch Dynamic AMOLED, 120Hz. Galaxy Note 20 Ultra: 6.9-inch Dynamic AMOLED 2X, 120Hz adaptive. Galaxy S21 Ultra: 6.8-inch Dynamic AMOLED 2X, 120Hz LTPO adaptive.
