Word, Excel, Photoshop and Acrobat are each better than Docuslice at the job they were built for, and only one of the four can split a document across several sheets of paper at full size. Here is where each one genuinely helps and where it stops.

Other tiling tools
Rasterbator and Block Posters both tile — that is what they are for. The question is not whether they can split an image across sheets but how much control you get over the result, and what happens when the source is a PDF rather than a photograph.

Microsoft Word
Word is a genuine design tool — text boxes, shapes, WordArt, alignment guides, a photo running behind everything — and it will let you build a poster-sized page up to 22 inches on a side. What it will not do is print that page at full size: the only sizing control in Word's print settings shrinks the document onto whatever paper is in the printer, and no image can cross a page break. Design it in Word, export the PDF, tile that.

Microsoft Excel
Excel is the best tool there is for getting a wide spreadsheet onto a stack of readable pages: Page Break Preview, Scale to Fit, Print Titles to repeat the header row, and page order. Nothing replaces it for that. Tiling is the other job — many sheets making one large picture, with overlap, cut marks and a real-world finished size — and that is where a chart destined for a wall leaves Excel.

Photoshop
Photoshop owns everything that happens to the artwork before it is split: colour management and soft proofing, CMYK for a commercial press, output sharpening at the final size, retouching and compositing. It has no tiling command. The manual route — guides, hand-corrected divisions, slices, one exported file per tile — runs to eleven or thirteen steps with no overlap, no cut marks and no numbering. Finish the image in Photoshop; the splitting does not have to happen there.

Adobe Acrobat
Acrobat's Poster mode, under Page Sizing & Handling in the Print dialog, genuinely tiles — with overlap, cut marks and labels — and it is free in Reader on Windows. Its limits are that it works in percentages rather than real-world sizes, that it produces a print job rather than a file you keep, and that since macOS Sonoma the option is widely reported greyed out in the free Reader on Mac. If Acrobat is on your machine and Poster does what you need, use it.

Rasterbator
Rasterbator does something Docuslice does not: its signature halftone effect turns a photograph into a field of dots that resolves into an image at a distance. If that look is what you are after, it is the tool — nothing here replaces it. What it is not built for is dimensional work. It thinks in sheets rather than in millimetres, so a poster that has to be a particular size on a particular wall means working backwards from the sheet count, and a PDF source is outside what it handles.
Block Posters
Block Posters is the fastest way to get an image split across sheets: upload, choose how many sheets wide, download. For a one-off enlargement of a photograph that is a virtue, and the simplicity is the point. The trade is control — the finishing that makes a large tiled print assemble cleanly, and that matters more the more sheets there are: overlap so a cut that drifts lands on duplicated artwork, cut lines and scissor marks to trim against, and numbering so sixteen near-identical sheets stay in order.
